Hi Simon - thanks for that. However, mine is a 2007 2.2HDI 173hp using PATfluid (176). Any ideas on getting the system to reset itself? Would a BHI reset solve it or is that something completely different?

When you say that the garage has 'reset the code', do you mean they reset the fault code / message? You also need to tell the car that fluid has been replaced otherwise it will think the level is still low.

No a BHI reset wouldn't help. The early cars were a pain to reset the system , even on lexia (had to replace the ecu on mine in the end), but it should be a lot more straight forward on the later cars as the functionality was put into the main ECU. Are the garage following the reset process properly?

I have read that some of the very early 2.2 HDi cars (could be yours?) have an ECU that can't be reset and has to be replaced.
Yes, you may have come up against this.

The DW12BTED4 doesn't have a separate ECU ; it was one of the big updates (along with changing the inlet manifold from plastic to aluminium)

One should always use the guide that I put up above as the systems used are based on vehicle build date - not engine type.

But on some of the vehicles the ECU could be a bit of a sod to reset. Who is doing the reset for you and are they using a Lexia to do it?

No, they don't have a Lexia unfortunately - rare as hen's teeth in this part of Shropshire. They have an Autel. Is that up to the job or is it limited with Citroen diagnostics?

I would really try and eliminate that as the issue by getting somebody to try the reset with a Lexia to be honest - that way you can rule it out.

Hi Marc,
just read your reply - many thanks as ever.
Actually, total success after all - another garage with a 'Snap On' diag box sorted it all in 5 minutes.

Excellent! Not all diagnostic tools are the same - evidently!

If you have trouble again, I have a Chinese Lexia and two C5s and based in Tenbury Wells. R
