Hi I've got a pre LCI 325d Msport with a M57 engine fitted.

The Dpf won't regen itself and after watching parameters I've noticed the engine temp won't reach the required 80° to perform the regen.

Am I right I'm thinking the M57 has the main thermostat situated at the front of the engine? And a thermostat for the egr?

If so am I better buying genuine BMW parts and what is good coolant?

Thanks

Hiya have a look at this

480A DFP 335d Error http://www.e90post.com/forums/showthread.php?t=1456927

There's a pdf that will help you.


What fault codes do you have?

I ordered oem thermostats. Get 4 new thermostat bolts as well.

Genuine bmw coolant is quite cheap so get a few bottles of that as well

always get bmw stats..egr will be easy to change but the main stat is harder,,while your at it id do the waterpump will be cheap as yours is mechanical..

Buy both from BMW, will be around £100.

Both relatively easy to replace, it is tight and removing the rad and fan will help (I did this on an E60 530D which is the same engine) That had a electric water pump so easier to bleed.

Hardest part was getting the rubber pipe off the main stat. Complete pain in the ass but eventually it came free.

£83 delivered for both for me,,although mines a pre lci,,probably the same
