Just changed egr thermostat, but engine still not reaching anywhere near proper levels.
Guessing I now need to change the main thermostat...? Is there anything else I can check before doing this?

Main stat mate, you will probs find one of the little plastic clips in the housing broken and the stat cockeyed!
I have just recently gone through this.
I broke the EGR stat so had to change it and it was the main stat after all.
Since I changed it the car stays between 88 and 90 degrees.
I think it was £40 from the BMW vendor on here.
Ok cheers guys. Is this an easy job to do, any guides anywhere?
Last week I did oil & filter change, this week the egr stat, air filter, turbo breather and pollen filter, quite enjoyable apart from the ridiculous air box design...
If you have a look at my build thread there are a few pictures that should help you get an idea of the job. Its not a guide though.
It was a real pain to get at the top stat bolt and they are a very small torx type, but I used a normal hex socket 6 or 7mm IIRC.
Edit: And yes you are correct, the airbox is a fucking ridiculous design....

It doesn't show the EGR thermo so you'll have to disconnect that before slackening the EGR pipe, on my old 2003 320d these 2 screws were T45 Torx fitment.

I did it without removing the EGR pipe from the exhaust manifold, just the intake.
Been busy lately so not looked at this yet. I did get a price from local indy though for part and labourHow much should I expect to be paying for this to be done? Do you have to mess about flushing all the coolant and putting it back in etc, as i'm not sure i'd be confident enough to tackle that just yet! But I am skint, so anything not too tricky i'll have a go at.
Are there any guides with pictures?
@Stal1878 I had a quick look at your build thread (for about an hour until I found the bit you were talking about...) sounds like you're pretty competent with a spanner, I might just bite the bullet and take it to a garage
but i am sleepy after reading all that... so might reconsider depending on opinions, guides available and garage prices!
It really needs sorting though, i'm getting about 28mpg real life... thats not good. My 20 year old MX5 gets that, and it never breaks... Been driving that around recently til I tuck it up for winter at end of the month, then back to nice comfy heated seated non drafty BMW![]()
Believe me Phil it isn't a tricky job mate, the worst thing is bleed the coolant system after refilling but jack the front end up as far as possible and follow the
bleeding instructions in TIS.

Haha Phil, sorry
It is a bit involved and its very hard to tell you to try it or not.
On my 328i, 330i and this 320d I have never had any problems with bleeding the cooling systems. I just put in as much coolant as it will take, start it up and let it run while adding more coolant if it drops. Opening the bleed screws on the EGR stat and by the expansion tank.
Draining the coolant is pretty easy, remove the front undertray, a few screws and some of those rivet things(might be hard to fit in there without jacking it up, but possible) and the drain plug is under the expansion tank.
Once you have the fan out there is plenty of room, but the EGR cooler will block the top bolt so its a tricky bugger to remove, but like I said I managed it with only disconnecting the EGR pipe at the intake manifold end.
What prices have you been quoted? I paid £20 for anti-freeze(the correct BMW grade), £40 for the thermostat and I suppose it took about an hour, maybe an hour and a half at the top end. A garage will put circa 10% on bits, and say 1.5 hours labour at £35 comes to about £120?
