S Type Restricted Performance on V6 Deisel

[Keith Raven]

I have tried a diagnostic reader to find out what the problem is or how to remove the warning, any suggestions?

The results from a reader will depend on how good the reader is. Some of the cheaper ones are not so good at finding/diagnosing codes, other than direct engine related matters. This could be a problem that is not directly engine originated.

I had a similar problem last year but found keeping battery charged up and a good long run sorted problem. Reoccurred again this spring did same again and no problem since.  If it comes back I shall trie battery charge alone to see if it might be electrical before driving it 50 milers along the M1 to cure it.

S-Types are renown for Parasitic Drain. You need to acquire a CTEK MS 7 charger/restorer and use it regularly. I put mine on at least once per month and for a minimum of 24 hours. Stops a lot of frustrating warnings and codes. Many people on this forum use and recommend the CTEK product.

Best Wishes and Regards, John

OK so my  carsoft scanner says it's high  outage on my A bank egr  and low  voltage on one of the Maf sensors  I'll delve into it further and see what turns up
