right I have a 2004 cmax with the blown engine out on the deck and have bought a replacement I did have the mark 1 g8da engine but now have g8db engine did not relise till it was delivered .........do I need the ecu to get it to run or can I just keep my ecu and change all the aux parts over........ noticed there is a throttle body on it on the intake and also the pipes going onto the egr valve are different

 

Send it back immediately or prepare for a massive headache and a car that will never run.

 

the heads banging anyway now and it cant go back, have it all complete with the engine loom and the ecu is there if needed and it fits in the bay..... must be able to run surely

 

Doubt it,the ecu will be coded to the key so will need recoded,you are saying the pipes are different as is the engine code so I'd say its a safe guess there are other differences.
I bought heated seats for a 54 plate mondeo st,the seats were from a 55 plate,plugged them in and they were hot all the time,turns out the looms changed across the years and could have caused airbag problems too so just because it's a 1.6 tdci doesn't mean it's the same thing.
The 1.6 tdci is bad enough without giving yourself more hassle.
What was wrong with the old engine and did you get the new engines turbo?

 

got a hole in the block massive... shot the rod........ engine came complete with turbo, turbo sensor fly wheel clutch starter everything but the g box so now I have two of everything , theres a key to go with the ecu and it will cost me peanuts suppose I could always try it and if it does not work good old ebay,

 

well I little update shes a runner

 

Do ford use a decent Diesel engine these days ?
What's their most powerful Diesel engine , the 163ps kuga engine?
Could be a nice upgrade over the 1.6 tdci engine ?

 

The 1.4 tdci in the mk7 fiesta and the 2.0 / 2.2 tdci in the focus + bigger models are all good engines. The 1.6 is well known for oil ways sludging up, causing oil starvation to the turbo.


All Peugeot engines mind!
