Hi Tony The 3.0 litre engine is quite thirsty but I would have thought it would have been up in the low 20's at least. You could look at a Tuning Box to enhance MPG...I fitted one to my Honda CRV cdti last week and it's now getting around 10-12% increase on MPG. http://www.diesel-performance.co.uk/ Cheers Trevor

sounds like the right sort of mods to start with.....look forward to seeing the pics. Cheers, Trevor

Hi Phil...welcome to the Forum A fellow Z3 owner, also going through the midlife crisis...which incidentally has almost lasted 10 years so far and thoroughly enjoying it! What size engine, colour, etc. is your new Z3 ? Post up a picture of it if you like. Cheers Trevor

The bigger capacity diesel engines are more than enough power to give a comfortable and relaxed drive but obviously a slightly lower mpg

The 5 series sounds like a good move and personally I would chip/remap it as soon as poss to release the potential power that's already in the engine. The autobox is certainly capable of transferring the power to the rear wheels without any issues.

Hi Richard...welcome to the Forum Sounds like a new fitting kit is required to take up the clearance between the pads and the carrier but allowing it to slide sideways with ease. Worthwhile applying Copperslip when assembling. Let us know how it all progresses Cheers Trevor

Hi Peter...welcome to the Forum What cosmetic mods have you done? Pop up some pictures if you like Cheers Trevor

lol...same here !

Hi MIchael...welcome to the Forum The 750 is a superb car and a welcome addition to your fleet by the sound of it. Post up some photos of your collection is you like? Cheers Trevor

Not entirely sure where the lines are but if the ATF has contaminated with coolant then chances are the cooler is part of the radiator (check for coolant level/loss). If so, then another radiator is required. If it is seperate, then the coolant hoses will be going to it (somewhere near the front lower part of the radiator.

Hi Andrew...welcome to the Forum Catch 22 situation. I suppose it looks awesome with the wheels tucking up under the arches but then as you accelerate then it rubs....catch 22 ! I guess the answer is to fit M5 springs to avoid this (less compliance) and still keep the look as you suggested. Let us know how you get on with it. Cheers Trevor p.s. would love to see what the car looks like if you want to post up a piccy of it, if you want

Hi Fred I'm guessing as you say the fluid is honey coloured that the fault may be with the transmission cooler (which may be part of the engine coolant radiator or a completely separate cooler). If this has burst, then that could be the reason for the loss of fluid and also mixing with coolant (if part of the radiator) resulting in the colour of contaminated fluid - emulsification). I would check the source of the leak before committing to replacing any parts...probably thoroughly wash underneath with a jet wash and brake cleaner and then fill with cheap fluid and run to see where it is coming from. Let us know how you get on with it Cheers Trevor

Hi Fred....welcome to the Forum Really knowledgeable advice you gave on the CanBus post...I guess you have many problems with BMW CanBus then? Great to have you onboard and feel free to jump in with responses to any enquiries...really appreciate having knowledgable Techies on here. Cheers Trevor

Hi Tony...welcome to the Forum It would be worth running a scan to establish the cause in case it is causing damage to the transmission. May only be something simple like a temperature sensor or low on fluid. Let us know how you get on with it Cheers Trevor

Okay, that's interesting...see how that goes then. Please let us know if that works out, cheers

Unless the ballast pack(s) are faulty?

It could be faulty wiring or corroded connections that are not supplying the relay with enough current as you say.

Hi Derrick...welcome to the Forum Not sure about just replacing the amp (with an aftermarket one) and keeping standard head unit unless of course the replacement is a standard BMW unit. This company has a good selection of replacement units, which would work with any aftermarket amplifier http://www.iceboxauto.com/bmw Let us know how you get on with it all Cheers Trevor

Hi Ian...welcome to the Forum It may become an issue when the car is taken for servicing unless the dealer offers a manufacturer recommended remap, which I know some manufacturers approve certain tuning mods. The same I would imagine for the lighting which could invalidate the warranty (if any). Let us know how you get on with this one Cheers Trevor

Not sure, but looking at my keyboard, the # symbol has ~ on top of it so maybe if you have the ~ symbol come up on i-drive then use Shift + ~ to give you the # sign

It's a shame you've had such a bad experience with BMW as I know some of the older models go on year after year with no problems at all. I do know they now source materials and components from dubious sources (regarding engineering quality and materials used) and some models are assembled by less than skilled operatives, so overall...I think it is no different from most manufacturers but BMW cost a lot more to put right if they go wrong

Hi Billy...welcome to the Forum That's an interesting question and one which I think you'll need to ask the Tuning company, as they may be able to map out the DPF settings to not be so sensitive in respect to the reduced exhaust system back pressure. Please let us know how you get on with finding a solution to this. Cheers Trevor

It may be tight but an extra 5% of the profile isn't too much bigger but maybe best to try one on first before committing to a set

Not too sure whether they would without offering them up to make a comparison....sorry!

Hi...and welcome to the Forum Look forward to reading your posts in the future. Cheers Trevor
