Yep. I'd agree, my 2014 had some issues with the locking, found several broken wires and wires with insulation cracked. DIY repair if you are comfortable messing about with wires/soldering etc. I suspect the passenger door and boot lid going the same way unfortunately...age, repeated bending/stretching and material quality all an issue here.

Worth a close look at the rear tyres, especially inner wall edge. Estates are very prone to camber issues causing sawtoothing/feathering and noise. I had this a while ago and a 4 wheel alignment sorted the issue. Tend to run the tyres at a slightly higher pressure as well, I'm using Crossclimates on my 4x4 Estate. Could be something else but worth checking the basics.

I've used a Carista reader for years, its been pretty good and definitely saved a few £££. I pay for the subscription version and would say I get good value out of it each year and will continue with it.

Hard to say, what sort of journeys are you doing ? (short/long) Does the engine get up to temperature fully ? My 2014 has the CFFB engine, the fix was applied by the dealer before I got the car (unfortunately!) but its been ok. Used to get 220 - 240 miles between regens but this has dropped to 120 - 180ish depending on journeys. I assume the shorter intervals must relate to gradual oil ash build up in the DPF.

A simple possibility could be one of the heat shields has dropped down. They are thin aluminium sheet and will create a buzz/rattle if loose. Worth checking from front to back. The clips rust through and can be replaced cheaply. I had this at the rear of my car. Also the exhaust sleeve in the middle of the system became loose, the clamps had rotted and it needed replaced. Hopefully be something simple.

A negative reading on the egr cooler sensor could suggest the sensor is faulty ? I'm not too familiar with the arrangement but assume the sensor could be replaced. Maybe it is failing safe and causing the aux pump to run continuously and over cooling the engine ? Just a thought...🤞

Hi, Interesting thread, for a couple of years my car has done this occasionally. Get out the car and close the door and the locking goes a bit wild, locking and unlocking maybe 4 - 5 times. Holding the unlock button on the fob seems to get it under control. It can be fine for a while then plays up again. It's been doing it a lot more recently and last weekend I repaired the wiring at the drivers door which were found with the usual broken insulation, chewed wires etc...couple of cables replaced, others heat shrink applied. Been fine all week until today and its started up again. Either my repair is failing or I'm suspicious the drivers door mechanism is faulty. I can close the door almost fully with no problems, but as soon as I click the door shut it then plays up. Suggests this is to do with the microswitches in the latch mechanism ? I'll be checking the wiring again and will also check the other doors but I'm suspicious of the latch. Anyone replaced the latch mechanism ?

Ah, apologies I hadn't realised where you are located ! Yeah sounds easier to buy new wheels ! I used a company in Kilmarnock (Stiggy Motorsport), dropped off 8am, picked up 5pm same day. Really pleased with the service and finish. My wheels are a dark anthracite non standard? colour but they managed to come up with a match.

Worth looking at getting your wheels refurbished (stripped, blasted and powdercoated). I had mine done 3ish years ago now, made a huge difference to the look and also no more losing air which was the main issue. Probably around £250 for 4, some places do a same day turnaround. Cheers

Afternoon all... Just had an issue with my (now getting on a bit) Superb after topping up the washer, the bonnet wouldn't latch shut. It just bounced back up when trying to close resulting in panic/stress as its needed for work.. I pulled the release lever and tried again and it closed this time thankfully but seeking thoughts on how to proceed without getting stuck with an open bonnet. I didn't want to re-open until prepared to deal with it to avoid being stuck... The release lever has been stiff for as long as I can remember despite regular dosing the latch mechanism with WD40/lithium grease spray, just assumed it was a Superb trait... The catch lever under the bonnet is very free moving as I know that can seize up. I guess a couple of questions - Can you get to the cable end to lubricate directly, couldn't really see ? Thinking I will direct copious amounts of spray into the cable end. Is there a joint in the cable or mechanism under the slam panel which needs lubricating ? Any recommended spray lubricant ? (I have been using white lithium with no issues until now...) Is it better to replace the cable entirely ? (anyone have a part number or diagram of the installation ?) UPDATE 28/02/26 So I have basically answered my questions with a bit of investigation and I'd recommend any Mk2 owner doing this as a bit of preventative maintenance. Cleaned up the bonnet latch with a load of brake cleaner which got rid of a lot of old white lithium grease that had congeled along with a bit or road dirt etc. Did the same for the release mechanism lever which was already free but did no harm. I then had a poke around and found the cable joint mechanism under the slam panel just above the nearside headlamp. This is held by a couple of clips which easily pulls off to give better access to the arrangement. I know that this housing is where the cable joint can get detached but mine remained intact. The housing clearly can come apart which means spray oil can penetrate so I doused about half a can of 'Rocket' spray into each end of the cable, and also all over. A rag placed beneath caught all the drips. I worked the release lever and immediately noticed a massive difference, it has freed up hugely and is now springing back as you'd expect. So this joint housing seems to be the cause of a lot of the sticking issues so a liberal douse of spray every so often should keep it free and might stop your bonnet cable becoming detached. Many thanks Dave

Thanks that sounds a good result. Was this via an independent garage I assume ? I imagine a main dealer would be 2 or 3 times that...! I'll need to look into it, currently got a door wiring glitch to deal with thats just started this week....🤔

Hi, Spotted your post as looking into a possible issue with the main thermostat on my Superb. Cabin heats up ok on mine, not a DSG box so reckon it must be the main stat needing replaced. Did your repair go ok, and what was they rough cost at the end of the day ? Thanks !

Thanks folks, I'll need to look into what's involved. Would likely get a garage to do this for me, time is very limited unfortunately.

Many thanks ! My car is a 2014 facelift model but I think they do one for this, bit more expensive at £49 though... My car is a manual 2.0TDI CFFB engine, been struggling to get up to running temperature since the weather has changed a couple of months ago no matter the journey type. Makes me wonder if the thermostat is faulty...🤔

Good to hear you're issues are sorted. Would you be able to share where you got your grille cover from ?
