My car 3 weeks went into limp mode , with Engine Service Req and High Emissions appearing on the dash. A local diesel specialist undertook to repair the car taking scans of the car with their Snapon code reader. They discovered that the EGR valve might be at fault so removed the EGR / Turbo and pipework and cleaned it all up replacing one seal. They had the car for over a week and eventually when I went back to collect it they admitted they had come up blank and suggested I go to a Volvo garage to get it checked over. They charged me circa £300 which I paid reluctantly after having to hire a vehicle for already a week. I asked ( having read on an informative Volvo owners website ) had they checked all the fuses and in particular Fuse 11 , as this can be a souce of the problem. I was reassured they checked every one but when I got home prior to calling Volvo I checked Fuse 11 - ang guess what it had blown ! I put a new on in (17p worth) and it immediately came out of limp mode. I took the car back to express my concern . They re-scanned and suggested I take it for a drive. All was well and on return the original fault codes were still there. The work they did hadn't removed the codes nor had the fuse , but importantly and significantly the car is fine. Had they found a blown fuse earlier and replaced it the car would have come out of limp mode for them too. Now we are in dispute as I think a gesture of goodwill should be offered. Our initial exchange was heated but I have put a conciliatory letter to them asking for a reasonable response as I now have offered an olive branch. My guess is they will completely ignore my overture. Any thoughts would be appreciated.
