What injection pump do I have?

I bought a Caddy with an Mtdi AHU and want to set the timing on the injection pump. Which IP do I have, and where should I set the lift? The cold start is on the "front" of the pump (the side on the front of the car). I didn't see any numbers on the front but there a few on the back, but an internet search didn't turn anything up. I saw another thread with Bosch part numbers listed for Land Rover pumps but I didn't see any of these numbers on my pump.

Chinese Bosch VE knockoff?
Honestly, no markings mean no idea...


You set timing mechanically via the access port on the distributor head of the pump, center bolt. You will need a lift gauge to set it, but what you set it to I have no idea since MTDI has no VW published standard since it's a custom setup.

Here's a detailed HOW-TO on setting the timing on a mechanical pump, but yup... there are no published specs since this is not a standard configuration... some experimentation will be required.

That said... there are other folks here running m-TDI set-ups... so a straight forward "What timing setting should I use for my m-TDI??" thread might attract some thoughts for you.

I'm guessing that's one of the Chinese knock-offs sold by Hans Auto

Yup - these pumps are all muts, you never know what you're going to get!

If it’s a Landy pump, most people set them around 1.5mm. I’ve never seen a landy pump, where the advance lever is facing the front of the car.

Are you afraid to remove some clamps and tubing? You’re asking for help, yet the pics are terrible.

I have a LR pump on my ALH and it doesn't look anything like the OP's. The lack of Bosch markings tells us it ain't genuine anything.

Those pics were from before I decided to start the thread. I did get a dial indicator and an adapter set for the middle bolt.I used to do this on my 1.5idi before the ALH swap in my other car. I'm having trouble uploading images but hopefully I'll be able to post more tomorrow. I had never considered that it could be a knockoff pump, definitely not thrilled.

It should have a placard that has the serial number and should say Bosch stamped if it's a Bosch. Never saw a Bosch part without it being stamped Bosch.
Try to get a good shot at the front side towards the radiator, engine side and, injector line side to see if there is one there.

Different pump, but shows scribe and Bosch on housing.

Actually that's the first thing came to mind when I saw it, a Han's Auto POS.
