get someone with small hands

no need to remove egr cooler, or air filter cover

if you have a flexible extendable wrench for the main stat screws, that'd be ideal, otherwise use a giant piece of metal to push the plastic piping forward to gain better access to put the main stat back on (look in my guide and the tool I used to do this (signature!))

use deionised water

 

shiiiiiiiiiiit, ECP? Return the main stat, they're defective and are known to fail within 1k miles, ask "chaz". In fact, return egr stat too, GSF do the OEM part for the same price. I don't know who supplies OEM main stat part from stealers themselves.

 

Follow the bleeding procedure from that bmw TIS is it called?

Blood, DONT!!! use the Eurocarparts main stat. It will fail within 500 miles. Check my others posts on here why. Before you fit it, return it, pay £10 more and get a BMW one.

 

Sorry, had not seen Baus' full comment. The ECP EGR stat I believe is OEM (Behr), but still - dont waste your time and coolant - you will need to replace it soon enough again, they have a known issue where the rubber climbs off the metal bit.

 

Here is the detail:-

Have you fitted them?

 

Watch your temps over the next 1000 miles or so - mine failed before it hit 500ish miles.

As said, I made the mistake of fitting ECP main and EGR stats, and the coolant temperature actually got worse! Had to pay all over again and had the job done with dealer stats.

try returning them to a store so you don't have to pay postage?

 

and if you're short on cash atm, then just fit the main, the egr can be fitted with ease at a later stage, whats more, a few people have found changing the main enough to get up to the full 90C, and not needed to replace the egr stat.

Blood, ive got an EGR stat here (original BMW) that was used to prove that the ECP one was either faulty or not. I wanted £30 for it but hey, if you need it, take it for whatever you want to pay for it. Return both the ECP ones, get the main from BMW and take this BMW EGR one from me.

I’ve got question: after what kind of distance coolant should reach 90deg+ ? I just discovered hidden menu and monitor coolant temperature, but have not done any long runs, only to work which is 6.5miles and after that it gets 60-68deg It’s that normal? I have change EGR recently so does it mean that main thermostat need to be changed?

40C after 2 miles, 60C after 4 miles for me, with new stats.

 

90C in 8-10miles (12 in winter).

monitored my coolant temp. last two days and while drive does not exceed 77-78deg, sometimes when stack in the traffic temp. went up to 85deg.

sound like need to replace main thermostat....From the forum search most of you recommend only genuine one, am I correct?

Don't bother with non genuine stats. Not worth the hassle. High chance the whole job will need doing again if non genuine stats are used.

I've only seen gsf do an oem egr stat which is a tenner cheaper from them.

I had geniune stats fitted six months ago.  Both were replaced yesterday as one or other of them had failed again.  As I was informed yesterday, genuine BMW stats have a two year warranty :-)

But if you fitted yourself, do they replace it themselves and give you coolant ?

My Indy said that as they were BMW parts, the correct procedure under a warranty claim with them would be for him to take the car to BMW and stand and watch while THEY fitted the replacements.  I'm not sure whether the "stand and watch" part was just him making sure they don't pull a fast one or not.

 

In the end, he managed to swing it for someone from the dealer to drive over the replacement stats and he fitted them himself so he could get the job done same day rather than me having to bring it back another day.

 

What that means if you bought the parts and fitted yourself is anyone's guess.  I would imagine it would cover just the replacement parts themselves.

You gotta pay for labour, coolant yourself? Hmmm, that sounds a bit unfair.

 

Exactly 1 year on, I've noticed my stats are about 3-4 degrees weak. Need to check properly though.

I'm taking a guess.  They could argue that you must have damaged them somehow during fitting.

jeez, these are pretty basic devices, it warms up, some wax melts and it pushes the valve out. Can't see any way to damage it. Luckily I have a video of when it ran at 90C in -5C weather, clearly demonstrating that it was installed properly... gotta decide if I kick up a fuss now
