A bit of a deep technical question. But maybe someone knows something I don't?
My understaning is that the IPK hardware and firmware is identical for all highline IPKs. The only difference is the contents of the EEPROM. I'm asking because I replaced the EEPROM on a petrol IPK with one for a diesel along with swapping the dial plate. Didn't work properly. My suspicion is I've done something else in the process, probably CAN ...

Hello all,

Could someone give me a steer please as to where this part fits? I am sure its part of the exhaust system and sits against the car bulkhead somewhere to stop it turning when screwing in/out a bolt. For the life of me I cannot work out where it goes. Its from a KV6 car.

Hi there. I am hoping someone may be able to shed some light on an issue I am having trying to replace the dipstick tube connector on my 2004 ZT with KV6 engine.
Rimmers list only one part number for the item, ( part number LYC 100510) which I purchased but was not suitable as the hole in the collar is not large enough for the tube to pass through. DMGRS stock the same part ...

I bought my latest 75 at the beginning of the year after doing all the necessary checks and asking all the right questions. It's a beautiful version - a 2003 Connoisseur Se Cdti - but after sale some undisclosed faults appeared and I referred to AA Mediation, about two months ago. It wasn't bought from AA Cars but from a seller who relied on AA Standards. The seller has finally agreed to consider a written ...

A good day to all!

I am at the point where I am now ready to refit my KV6 Engine back into the car - Hoorah.

Before I do I am trying to locate plug locations for ease of fitting once the engine is in, at the moment I am struggling to find the plug for the downstream oxygen sensor within the wiring loom.

So far I have identified one connector on the front right ...

I have a s/h working alternator from a Rover 75 CDTi classic saloon (low spec but that worked well) but not sure if this alternator is good enough to fit on my present CDTi because I am not sure if the slip rings are too worn or discoloured? From searching the web the copper slip rings should not be discoloured. If so there is no point in me changing the regulator which includes new brushes? ...

Artic thinks Duncan is the man in the know for this.

I have an early Facelift Tourer and a late Facelift tourer.
It could be T4 programming.

Late Tourer, 1 short click, only drivers door unlocks, second click, all doors and tail gate unlock. 1 long click and drivers door and tail gate unlock.

Hello all - I find myself in need of some advice please.
