I all, it's my frist thread on this forum normaly i find all my answer in the howto but this one is hard to solve.

I have a 2000 TDI manual tranny converted.

Get some limp mode in the last week but solve it with the change of some vac line and clean the MAF with MAF cleanner.

Yesterday a new problem start, the car get no power (not limp mode).

Code
16629 P0245 N75 short to ground
18027 P1619 J52 short to ground
17849 P1441 EGR short to ground
16600 P0216 N108 Valve inj timing

If i disconnect the MAF
16629 P0245 N75 short to ground
18027 P1619 J52 short to ground
17849 P1441 EGR short to ground
16486 P0102 MAF Low signal

Look a all my vac line
try a other uses MAF

Got 12volt on the yel/blk wire

Scan the MAF the value are close when i start the car but once the normal value go to 850, both MAF never go over 400.

Hope some body can help me.

They alway come back... work on the car today.

Change all wiring that look worm. Test the VAC and have 30 or more.

make a new ECM ground.

connect the vac line to the N75 (by pass egr)

I'm short on idea

2 time i start the car a got turbo before the engine light come in, about 20 sec (With the MAF disconnect)

Test the shutter valve with a freind and it's work well.

Do you think my ecm is bad?
