Hi
New here after recommendations.
So, It's a 1999 (Smiley) Mk5 2.5 TD with 76,000 miles Autosleeper Motor Home.
The timing belt was replaced about 2000 miles ago.
The engine warning light started to come on after about 50 miles of motorway driving at 60 - 70mph.
The result was a loss of power (limp) but still drivable apart from on hills where power loss was massive.
After turning the engine off and then back on again we could carry on but the light would eventually come back on.
We've found that If we keep off of the motorways and don't rev the backside off it (keep under 3000ish revs) the light stays off for the most part.
We Just got back from a 300 mile trip around the Peak District keeping away from motorways and duel carriageways and it didn't come on once.
We've lived with this for a while now but keeping under 55mph is a pain so we'd like to fix it if poss.
My mate (young mechanic) checked the fault codes and found P1176 - 1178 and 1174. He's good but admits he doesn't know old diesels.
After a cam belt change I understand that if the timing is not spot on then that can cause these types of problems.
If this is the case would re-doing the belts and making sure the timing is spot on fix it or does it indicate that the diesel pump is done. It is the EPIC pump.
Hope someone can help
Thanks in advance
Adrian
