I'd say drain the fuel filter out into a jar and have a look what's in there for signs of the diesel floating on water or any weird colours from the car wash detergent (they'll probably sit in or on the diesel rather than mixing with it). From there on in, it depends how cautious you want to be. Full blown worried, would be drain and refill the tank with fresh diesel. Not mildly concerned would be just carry on and see what happens. I'd probably just keep the tank topped up as much as possible for a few thousand miles. If you did North Wales to Essex since you filled up, I'd be inclined to say that anything really, really bad that was going to happen would probably have already happened, but then I'm a bit of a fatalist.

Pop the diesel filter open and see what it's like in there. The lift pump slowly died on mine and when it finally went, it would run until the filter emptied, then if I refilled the filter, it ran fine for a few minutes until it ran low in there again.

My guess, and it is only an unqualified guess would be that they leave an electrical load on as a matter of course so cars with Stop-Start assist don't turn themselves off while they're in the air. You need the engine running to look for leaks in the exhaust system. The other reason they want the car running throughout is to make sure it's warmed up for the emissions test.

The cigarette lighter normally runs all the time on VAG cars. The normal way of wiring the camera in is to use an "add a fuse" in a spare switched circuit. A dashcam can drain the battery down surprisingly quickly.

The 1.6 is the AEE, the more common version is AEA, found in rusty MK4 polos, which is single point injection (the AEE is multipoint). The basic engine is the same though, all the injection system is on the inlet manifold. Careful if you're buying one out of a golf, some have the same 1.6 as the polo, others have a taller block. A few people have fitted the 1.4 16v polo engine.

Turned out to be a massive coincidence. I changed the air flow meter, and the lift pump died a day later

So, none starter at the minute, so I couldn't get a proper read, but I did a little live data while I was cracking it over... No fault codes from the engine, but like I say, none-starter. MAF showed data, seemed to move about a bit as the engine had a splutter. Throttle pedal sensor's working fine. Throttle position sensor is saying 100% all the time, even which the throttle body cycles as I prime the ignition and then turn it back off. Is that TPS figure normal? Is there a lonk between AFM and TPS?

So, it wasn't that simple.... Drove it to Nottingham yesterday. When I went to come back, the engine light was back on. Drove back fine apart from one little sort of flat, misfirey moment between 5th and 6th. Rough to start this morning. Then as I was going up hill a few minutes from the house, it misfired then cut out, wouldn't restart, or would restart briefly while the pedal was down. Pulled the AFM plug, no different. Pulled the fuse out (none blown), no different. Managed to get it started and drive it briefly, but as soon as you come off the pedal, it cuts out. Starting to work round things that I could roadside with the very basics. Throttle stepper is actuating fine and looks clean. Smokes when it's cranking but not starting, so I'll say it's getting fuel. Just waiting for recovery to drop it off, then I'll try and get some fault codes and live data at least.

So, the AFM wasn't getting power, so I bodged a temp feed to it. The car ran rough for a few seconds then settled down. Checked the fuses, blew my tiny mind on the left to right mirror because the diagram's for a left hand drive. Got set right by Nige - big thanks for that. Stuck a fuse in 29 (didn't have one). Drove down the lane, the fault light went off and stayed off for my ten minute drive home. I haven't had chance to scan it again, but I've got a couple of hundred miles to do tomorrow, so we'll see what catches fire between now and me getting home.

I'm going with boost leak.

Thanks for that - BXE rings a bell, it's not BJB (just because I know it's different to our old Caddy). So (after fuses) in the first instance, I'm looking for a straight 12v down pin 2? I'm just wondering if it's 3,4 or 5 that's not going through, if that coincides with the glowplug fault at a multiplug or if they go straight back the ECU?

Thanks @WinoIt's a 2008, can't think what the engine code is off hand, will check in daylight and come back to you. I'll bleep-check all the fuses in the morning just to be sure, but I think I did that when I bought it.

Car is a Mk2 Octavia 1.9TDI 105ps DSG Since I've had it (about a year), I've had the following fault and an engine light on the dash. 000258 - Mass Air Flow Sensor (G70) P0102 - 000 - Signal too Low Live data reads 0 at any engine speed. I originally assumed it was a faulty sensor, so I changed it for a Chinese one, which I think knocked the light off for a few hours (long enough for an MOT test), then it came back on, so I assumed the sensor wasn't great. Today, I live-data'd the MAF on a scrap Ibiza I've got in the yard, and it seemed to be working (went up and down as the engine speed did). The part number was the same except the suffix (-B on the Octavia, none on the Ibiza), so I decided to give it a try and throw it on. I cleared the codes on the Octavia, and the light came back on shortly after, with the same code, and reading of 0, regardless of engine speed. Here's the engine codes it's giving. The overboost is a new one, but I do remember nailing it with the trailer on a couple of weeks ago, so maybe that caused it. The glowplug one's been there forever. From what I understand, there's a known issue on these cars with the glowplug wiring loom? Car runs fine, a little rough when cold on a cold morning, but to be expected from an old diesel with no working glowplugs. Drives fine, gets 60mpg. Just puts the light on because of the MAF. 6 Faults Found: 000258 - Mass Air Flow Sensor (G70) P0102 - 000 - Signal too Low Freeze Frame: Fault Status: 01110000 Fault Priority: 0 Fault Frequency: 1 Reset counter: 255 Mileage: 296523 km Time Indication: 0 Date: 2000.00.00 Time: 19:06:50 Freeze Frame: RPM: 798 /min Speed: 0.0 km/h Load: 0.0 % Duty Cycle: 64.7 % Bin.

It's a bit of a rough way of doing it but.... Make sure the fluid it topped up. Get an assitant to pump the clutch about 10 times as harshly as you like. On the last stroke, hold the clutch down. Get a jam jar with some brake fluid in and a bit of hose that's long enough to be immersed on the brake fluid at the end. Put the hose from the bleed nipple on the slave into the fluid in the jar. Open the bleed nipple. Get your helper to pump it about 10 more times, hold it down on the last. Close the bleed nipple, top up the fluid. There's no reason it should work better than pressure or vac bleeding it, but I've had it work a few times on cars that wouldn't bleed up right using the proper tools.

SDI camshafts don't normally wear like PD ones do, so I wouldn't be in a rush to change that. Yes, always worth soaking new lifters. Normally I prime an oil system by turning the engine over, but not starting it. On an SDI, I'd unplug the stop solenoid to allow this to happen, but I can see why people might disagree with me on this.

It's possible. Either that or some sort of contractor's vehicle that had chevrons on? Quite often, they'll apply an oversized sheet, then trim it down, so what you're saying would make a lot of sense. Alternatively, someone might have been a bit rough taking a rear windscreen out to replace it. Just from one of the jobs I used to do, 6 months ownership would make me think it was either a hire (not necessarily a bad thing, it could have been one person's company car the whole time), or a demonstrator or pre-reg'd car.

Yeah, it's about as high as a standard felicia will go. New shocks and springs will help a bit, and you mentioned those spacers. They are pretty good offroad as they are, especcially if you put some mud and snow tyres on.

Just realised, I never asked what engine's in it? The diesel engine is heavy, 1.6 lighter, and the aluminium 1.3 the lightest of all.

There's an old lad with a felicia down the road, who's just had the wrong springs fitted on the front and he looks to have about 4-5 inch of arch gap I'm trying to remember if pickup springs fit in the car spring seats. It's probably as easy just to order a full set of springs for a 1.9D pickup truck if they do.

Diesel springs on the front and estate springs on the back should do it.

I'm getting two stories on the subject of changing the heater matrix. Some people say it's like a Golf and you have to have the whole dashboard and half the interior out. Others (mostly with LHD cars) say you just need to take the trim panels in the passenger footwell out and be a bit dexterous. Anyone got any hands on experience of doing one of these?

Mk1 Fabia Polo 9n (bug eye) or 9n3 (facelift) Ibiza 6L Fit new top mounts while you're there, and it's well worth changing the console bushes for Ibiza Cupra ones. https://www.darksidedevelopments.co.uk/products/ibiza-cupra-uprated-console-bushes-for-vw-polo-skoda-fabia-and-seat-ibiza.html You'll also want a spreader tool for opening the hub up where it clamps on the shock (you can crack the hub if you try to spread it with a random chisel. This one's a pair of Sealey ones, so good quality. You can buy cheaper if you're not planning on using them much. It's worth having a new pinch bolt and nut to hand for the same place in case the old one doesn't come quietly. Febi part number 27876 https://www.vwspares.co.uk/product_info.php?products_id=953

Any sign of oil that might have come up the breather in the air intake piping? Any smoke on startup when it's been sat overnight? Piston ring issues do happen on the 1.4. Take your spark plugs out and see if there's any oil on them, and their general condition. Might be worth doing a compression test if you've got a guage.

I have a few bits of wood flooring. Goes under the boot carpet without leaving a bump, stronger than it looks, and if need be you can stick a bit of gaffa tape round them to make a thicker peice.

That's the question, and I suppose really it depends what amount of space you're happy to work in. A decent pair of ramps is probably your best bet if you're doing the job on the driveway.
