I change mine if it doesn't get passed 87ºc, if you only get to 80ºc it is truly knackered.

Hi gIzzE,

It's been a while and just wanted to say I purchased both the EGR and Main thermostat from BMW and I'll be replacing them int he next few days. Was a little busy replacing the crankcase breather and air filter as well as cleaning the MAP sensor.. Very interested to see the figures on a motorway run after

[gIzzE]

Look forward to hearing your report.

Hi mate,

Apologies, I started a new job not so long back and I've neglected the forums haha.

Okay so new stats and I was amazed at how they performed, so in just a few minutes the temperature can get into the 70's and in a short amount of time the new stats locked in 91 degrees and I mean it was pretty much rock solid 91!

I've had the stats for quite a while now and my temperature sits between 88 - 91 and the temperature from the moment I start my car just increases.. before I could hit 60 - 70 and then the temperature could sit at a certain temperature or even drop a few degrees but good working stats don't behave anything like that it's just a nice linear increase to operating temperature and it keeps it there.

I was told by the dealer who I purchased the car from that on the motorway the temperature would never reach 90ish degrees because of the amount of air that hits the radiator.. that was completely wrong, on the motorway it gets straight up to temperature and sits between 88 - 91.

As for fuel economy I've not noticed any difference, £20 still returns 80ish miles (short journeys + town driving) and my MPG despite resetting every now and again will always settle at around 22MPG. I do believe however there is an underlying issue causing this but I'm still on the lookout.

Hi mate,

Cotswold quoted:

Both thermos will cost you £88.81 Inc Vat,Discount and Delivery to Mainland UK.

Main thermo is £52.66
EGR Thermo £36.16

Installation is pretty simple but took me bloody ages! One of the pipes that connect to the main thermostat has a rubber O-Ring in and that come away and it's fixed into place so I had to purchase another pipe which cost around £52! It's also the two bolts on the EGR cooler that's connected to the exhaust manifold that was really hard to remove.

im getting around 500 miles for £60 of diesel at £1.15 per litre which is £5.25 i think so about 11 and a half gallon.42-43 mpg..which is pretty good.was only getting around 35-36 mpg before i changed both thermostats .

have you done a hidden menu temp test while driving?just to make sure its getting to 90-93 degrees.i know its town driving and the auto box,but just to make sure ya getting maximum mpg.

I literally have a 10 mile round trip commute every day, it doesn't have time to get up to temp before im turning her off! Its always fine on a run though so not worried.

surprised you have a diesel car..maybe a petrol would be better.dervs usually have higher parts costs etc how many miles per year do you do?

It does about 4/5k a year, I always take my mrs A3 when doing any decent mileage.

I just prefer diesels! Its the Torque mainly but I am considering changing to petrol next time I swap, I cant see that being for a while however!

I would start using it, otherwise you may have some expensive problems in the future.
Also, with people now able to view the MOT history and see how many miles a year you do, I certainly wouldn't buy a big diesel that has only done 5k a year.

Averaging 29MPG in a 2007 E92 320d auto. It's my first week driving it, so haven't tested it too much apart from commuting to work in it this whole week. The commute is terrible going from Havering to Nine Elms, all across London at rush hours in constant start/stop traffic for an hour and a half but I was still expecting slightly better fuel economy, or is this normal?

It's my first ever car so I'm not sure what to look out for to determine if there is something wrong with the car, or if this is the MPG i should be expecting from that sort of driving.
Haven't had the chance to test it out on an open road motorway for a decent amount of time yet to see what it returns on that.

Just returned from a two way trip to Munich.Computer averaged between 50.5 and 53.3.Running at speeds up to 130mph
