Yes, that's the right hose to be checking, and yes, looks like the correct fuel filter is fitted. Maybe try a compression test if you have a tester?

Have you sorted yours then, by recoding, @badablade900? If so, that's very useful info to know.

Message me with your VIN and I can find correct part number for you.

Are you having any trouble with the alarm?

Well done. Interestingly the wiring info I'm looking at for CHPA shows four individual pencil-type coil packs, one on each spark plug. So that begs the question, which did they change, any?, all? Given the other (underboost) fault code, and the multiple random misfires, it's tempting to think the cause may be lean mixture rather than electrical/electronic.

Scan it and perhaps see a glowplug fault that isn't bad enough to yet put the fault light on.

3 or 4 letters on the front of engine number on V5c certificate.

Hall sensor rather than reed switch, according to ETKA, at least on the OP's car. Potayto/ potarto though.

You did have a different selection of fault codes, but it's a very easy thing to check, and fuelling could easily be imagined to be relevant here.

If the door lock motors' wires were actually present in the front door bellows you would definitely be able to unlock it by applying 12V in the correct polarity to the motors But they aren't, they only go between lock module and door control module as The Client correctly pointed out on page 1.

Claims to be a replacement for the relevant genuine part numbers, but very cheap in comparison! What caused you to replace it?

Check that your fuel filter has not been incorrectly replaced with a 3 bar version. From recent experience, the BME engine uses a 4 bar fuel filter. PM your VIN to me for checking if you find a 3 bar filter fitted (stamped into one end, it lives just in front of fuel tank, visible under car ahead of rear right wheel).

Where did the replacement MC come from? Part number?

Warm up time will be slightly longer, mpg may actually improve slightly without EGR flow. Only on petrol engines can it save fuel as well as decrease engine-out NOx.

It must be detachable from the cylinder as the parts catalogue shows it as a separate part. So if the cylinder is working hydraulic-wise I'd hope you wouldn't have to remove/replace that part? Any chance you just forgot to plug the connector back onto it?

Did the replacement master cylinder come with a hall sensor clutch switch, or did that get transferred across from the old one?

I'll be able to see if it was or wasn't built with a DPF, and associated sensors.

The asterix * is defined as "According to equipment". This might mean that your car has instead a G85 sensor on the steering column, nearer the steering wheel.

Hmm, having looked at wiring diagrams, I'm now wondering if your car even has an angle/turn rate G250 sensor on the rack. Can you have a look please? It'll be on the driver's side on the bit that goes up towards the steering column. Or is there a cable connected to the 3-way connector on the pump?

Yeah, there's an emergency mode it can go into that still provides some assistance even if there's no angle sensor info. From the relevant SSP doc "Substitute function If the sensor fails, the power steering moves into a programmed emergency mode. The steering function is assured. The steering is slightly heavier to operate."

When you say a new pump was fitted, do you mean brand new, or 'another pump'?

The only coding for the pumps is the 'steering weight' which is adjustable within a small range. Nothing that would make it not work, nor generate a fault code relating to the angle sensor. The simplest explanation of what you're seeing is that there is a fault with the turn rate sensor (G250) or the wiring to it, or connections at either end thereof.

Great result, especially given the doom and gloom posts some of us offered you.

Leave the bolt (golf tee also known to work nicely, if available) blocking the EGR vac hose for a few days and see what happens. You'll get a fault light after a while I assume, but not sure if anything else will happen like limp mode. Easily discovered by experiment.

Swap the calipers left to right.
