So, after having read all about everyone else's symptoms and read all the "how tos", it's now my turn.
Mine's got a full service history (ex-fleet car) and 83K on the clock. Yesterday morning, as I started driving to work, I noticed that not a lot was happening when I pressed the accelerator pedal under 2000rpm, until the turbo cut in. Then, on the dual carriageway, I was in 6th gear and wanted to overtake so put my foot down but the power actually lifted off rather than increased and the car/spanner warning light came on for a few seconds. I guess it switched to the "emergency running programme" briefly. The manual is a laugh, page 188 says "If it [the light] illuminates briefly, but does not recur, it is of no significance". Yeah, right.
It did it again on the way home, so I popped into my local TMC in Towcester to buy some carb cleaner, with the aim of doing some remedial work last night, but they'd run out. It was still the same this morning (although the first 100m was OK) so I nipped into Halfrauds on the way to work this morning and bought:
Wynn's Fuel Injection Intake & Carb Cleaner
Redex Diesel Advanced Fuel System Cleaner (3K mile treatment) (although now in gold packaging like this one)
Comma Multipurpose Grease (I'm sure it will be needed at some point!)
So, this evening I will be using the great "how tos" to remove and clean the boost sensor and EGR. Then, when I fill up with diesel later in the week, I'll chuck in the bottle of Redex. Hopefully the car will be back on top form then and I won't have to think about the pain of DMFs, manifolds and swirl bars... I nearly bought the de-coke can as well, but I thought I'd start with the above and see what happens.
I've just had a look at the EGR replacement poll and see that 135 people have had theirs replaced and 127 haven't. Many more appear to have cleaned theirs but I can't find a poll for that. What I want to know is, if this is such a known and widespread 'condition', does a full service not include cleaning the boost sensor and EGR? As the car only has a full service every 40K miles (with an interim of fluids and filters change every 20K) it would seem logical, so are they not done and/or do they just need cleaning more often than that? Perhaps it's a way for the stealer to get a few more £££ out of us for a new part? I have a year's warranty with the finance I took to part-purchase the car so I'll be checking that very carefully this evening to see exactly what is covered, just in case...
I see that short journeys and idling whilst warming up in the cold are big contributors to these problems, both of which have been happening since I got the car what with the cold weather etc. My journey to work is 14 miles, which takes about 20-25 mins. I thought that the engine took 5-10 mins to fully 'warm up' but does that count as a 'short journey' as far as this problem is concerned? I haven't yet done any long journeys, i.e. over an hour of continuous driving but I do get 'up to' 70mph () on my journey to work.
