After a series of poor running issues it went back to the dealer who diagnosed a marginally faulty EGR - previously I have had the EGR off twice and cleaned it, function seemed fine to me but I am assured that it wasn't working at 100%.
The EGR has been now changed at the dealer for a brand new one (bill not in yet - long story) but after picking it up late on Friday (ie. just as the garage was shutting) the car started coughing and spluttering after just a few miles. It was like a cleaning lady who used to work at my old offices in Aberdeen who smoked 40 JPS every day, short bursts of normality followed by coughing and spluttering for hours.
Anyway, it smoothed out a bit when on the open road but I whipped the new EGR off anyway on Saturday to find the old gaskets had been re-used. The gaskets were sealing OK but I was surprised as I thought they'd fit new gaskets. I had an ebay special EGR flow restricting plate/gasket (rather than a full blanking plate, not a good idea on the 16v jtd) to fit to before the EGR and once this was done and it went like a proper rocket again, very smooth, very nice power delivery.
Until yesterday that is. Sat in traffic at lunchtime the dreaded MCSF light came on
Fortunately I have a loan of an obdii hand held diagnostic 'device' that reads and clears error codes made by Sealey. Plugged it in and the error code was showing low flow at EGR. Cleared it but the fault reappeared last night when I got home, 15 miles of driving no issues but as the car sat at tick-over whilst I opened the gate up came the error again. With my first coffee this morning I cleared the same code down again. Guess that flow restricting gasket will need to come out, get 'reprofiled' with a bigger hole and refitted. Or I might whip it out completely and fit one between the EGR and the inlet manifold. I dunno, I'm getting bored now
Suspension work next, or 5 litres of super-unleaded and a box of swan vestas
