Hi all
54 plate 2.0 TDCi, manual,90k miles. Does this sound like an EGR problem as it fits some but not all of the symptoms discussed elsewhere...?
Twice now after a fault free run, the engine has refused to rev above 2000-2500rpm. The turbo never 'arrives', so driving is not impossible, but is 'fun' (max speed in 6th is about 72...). The Engine management light comes on (only the next time the engine is started - not during the first event whilst the engine is running). Acceleration to 2000rpm is almost normal, but the engine then simply refuses to pull any more (its like hitting a rev limiter). It is aslo a bit lumpy at tickover, though not too bad.
I never have starting problems, and the engine is not noticably smokey. The first time this happened (a month ago)it went away after 24hrs and a long motorway run. It happened again yesterday andI've just driven 90 miles to work on the motorway (at 70 mph but,hey, I got 56mpg!) and after restarting the engine in the carpark, it appears to have cleared again (management light still on but last time it stayed on until after about 3 normal runs)
Previously, after it cleared, the engine ran perfectly.
So.... is this an EGR problem? I'll get the AA out when I get home on Thursday, but in the meantime have ordered some EGR cleaner off ebay. Getting to the valve doesnt seem too hard - but do I just disconnect the silver pipe at the back of the enginethat leads to the manifold on the front, and spray it in to the valve with the engine off (I assume the valve is around the back?). Is there any need to spray anywhere else?
The only other thing I can think of is a turbo leak as it can be a bit 'whistle-ey'. Wheres best to check for that sort of thing?
Hope that all makes sense and ta for any advice!
