Lots of little jobs to do to get a CDTi running as it was designed to do.

1. EGR clean out and maybe disable/bypass.

2. CDTI worn thermostat's open too early, replace with OEM or put an extra one in the top hose.

3. Clear out the plenum and make sure it stays clear, or it may wreck your week.

4. PCV filter choked up, could wreck your turbo.

5. All of the above could cause smoke, but usually the MAF will have failed too. Unplugging it might help prove it, but best if it has failed to replace it. Don't be fooled by the many fakes, copies and etc.. read up (see below) and buy one from the MAF-shop in Berlin, the only known source of the genuine item.

6 Do the viton o ring replacement at the intercooler.

7. The Intercooler to EGR pipe is known to become soft and porous and even split - worth replacing.
