I've not seen what the ABS sensor clearance is - but I'm guessing not large - excess float in bearing could conceivably change gap sufficiently to trigger fault. As the pad to disc clearance is also very small, worn bearings could be causing excessive contact.

Not sure with the MPI - but believe that it is only the TDIs that run the water pump off the cambelt.

How do the wheel bearings feel on that side?

I was wondering about the possibility of the fuel filler angle being slightly lower than normal with the rear spring broken on the same side.

^^^^ + this - and there are a number of references on the forum to a failing crankshaft sensor not raising a fault code when engine fails to start.

No, but the front assist does. AFAIK, ACC uses the front assist radar to operate it - I'm not certain if ACC retrofit also requires a certain model of front camera (A5) but I have seen references to ACC being successfully retrofitted.

Try a PM to @East_Yorkshire_Retrofits for feasibility and cost.

Try a search on the forum - ACC retrofit.

Do you mean crankshaft position sensor? (rather than 'Camshaft') - this can apparently cause the issue of diesels cranking but failing to start - and seems fairly common.

There are members on this forum who can decode what options are factory fitted from the VIN.

Provided the indicator lights do extinguish when the engine is started, nothing to be concerned with - normal operation.

If ACC is particularly important to you, a retrofit is usually possible and may be worth considering.

In your case, at the very least insist that your fault complaint is recorded as having occurred before expiration of warranty. Given the known nature of this fault, personally, I'd be insisting of more extensive test by the dealer.

It may seem rather improbable, but it will be interesting if your fuelling issue goes away after the rear spring replacement.

It would be best to get the battery properly tested first before considering replacement. Does the engine appear to crank at normal speed when it fails to start? I'm concerned about your reference to jump-starting another vehicle before this issue first occurred, are you certain that you followed the correct procedure when you did this?

Did the RAC responder actually test the battery?

'Voltage terminal 15: 11.3V' looks low - does stop/start work, have you had the battery tested?

Is this a TDI @Jd89?

I believe that is the turbo actuator - unlikely to be the cause of your excessive oil use, does there appear to be low power output from engine?.

Hello Lukos, welcome to the forum. The 'engine must be running' message just means that the automatic idle stop function has been inhibited and the engine will remain running - there can be a number of reasons for this; low battery charge state/high electrical load, low or high cabin temperature, etc. A failing crankshaft position sensor (not camshaft) can apparently cause your symptoms - and may not log a DTC code.

Does the rear of the vehicle appear to squat excessively when the van is hooked up? The 'clunk' could possibly be from the rear bump stops.

That sounds like clutch-drag from plate not releasing fully - or contamination of clutch lining.

In that case, I suggest you look for a good independent garage.

Provided there is ample tread and the rubber is not displaying signs of significant degradation, there is no need to replace tyres, based on age, below around 10 years.

Unless you intend to change the rims as well, you will have to use R16 tyres.
