After fixing the rear wiper issue, drove to work, the engine shook a little on the first cold start, the light came on, engine management! aaaaarrrrrr!

I got home from work, plugged in VCDS, scanned, and two were faulty.

I bought the car last month, all is fine, but suddenly I have two errors this morning weird. I have purchased the glow plugs and rocker cover rubber seal, as my car is PD, not common rail. What about the mass sensor? replace?

Not sure re mass sensor but mine had failed glow plugs. Only spluttered/juddered on cold days but my mechanic mate did say that a failed glow plug can put EML on. Probably similar as it was a 1.9tdi pd. Before you change them he suggested some penetrating oil/engine oil around the plug for a few days and let it soak in while drivin and then remove them when engine is hot. I would replace glow plugs and reset codes and test drive. Hopefully you wont need to replace sensor.

MIght be worth unplugging MAF and cleaning contacts and reconnecting. I had a Volvo 940 that had a problem with the MAF but after cleaning connections it was fine. In my case it wouldn't rev more than 1500rpm Was a very slow drive home in first gear
