mr-modster · 12-04-2013, 01:52 AM

Hi guys im about to to purchase bmw extended warranty for my 335d the only problem is its been remapped would this invalidate my warranty? Are there any ways around this? Cheers

Get a map which you can swap out for the stock map within 5 mins yourself
Certain companies do these, they come on a small device which plugs into the OBD, and uploads

Tht way, if you need to go to BMW, just swap to stock map then swap back after

mr-modster · 12-04-2013, 02:45 AM

So how can I go about about getting this done? Wheres recommended? Can my map thats in there now be removed? I dont know where the previous owner got it done? :s

Can you ask the previous owner ?

mr-modster · 12-04-2013, 03:04 AM

No I haven't got any contact for him anymore unfortunately

HeavyRightFoot · 12-04-2013, 03:14 AM

I used Evolve for mine, have switched to standard map for services, MOT and any warranty issues. Built into the program is an error code reader and deleter so I just clear it all before taking it into a dealership. Also helpful to diagnose any problems.

Not sure about returning to standard map without the original but it'll probably be doable. Someone better at mapping will be along at some point to give you a more concrete answer I'm sure.

confused.com · 12-04-2013, 03:15 AM

I know from experience those so called devices that allow you to remove the map and go back to standard leave a trail of error codes - even the devices that supposedly allow you to remove the codes. If you were to have an engine/ecu issue, BMW would at first glance be able to see something untoward had taken place. ideally you need to see an indy who can remove all the codes properly after a flash - but having said that, once mapped, if BMW were on a mission, they can find out - all the decent tuners will inform you of this.

Heavy right foot - what warranty work did you have done out of curiosity?

SO8 · 12-04-2013, 03:26 AM

Jason at BW Chiptune in Hayes can put a car back to std I believe without the original map / remap again. He does a switch I think (just like Evolve in Luton) but only for cars without the newer ECU's ... which is the same as all the other mappers.

As has been said, the switch variety leave traces of their use.

HeavyRightFoot · 12-04-2013, 03:28 AM

I've had the water pump replaced and a coil pack replaced. Also had car in for 2 services and 2 MOT's.

You are probably right, I can well imagine if BMW wanted to look into things in greater detail they probably could find evidence of a map.

Also mine was the Evolve R for a 335i, which was a program on a lap top with a cable.

mr-modster · 12-04-2013, 03:39 AM

My car is a 2008 e92 335d would this have the newer or older ecu?. By the sounds of it I might be in trouble. I know theses cars are not known for there reliability

SO8 · 12-04-2013, 03:44 AM

A 2008 car should be able to be done via the OBD port - so a switch could be used.

I had a 320d done this way and the unit from Superchips removed all but I think 3 error codes. Basically there is a small amount of time when the main ECU swaps to the new map - or back and this effectively turns it off for a split second. This loss of connection with the main ECU shows in other control units in the car and not all of these error codes can be removed by the handheld unit supplied by the likes of Evolve or Superchips (as they can't connect to all of the ECU's).

My car had these error codes in the ABS control unit and the Auto gearbox control unit. These would be signs it had been mapped. I used a £8,000 Bosch diagnostic computer at work to get rid of my excess error codes

mr-modster · 12-04-2013, 03:53 AM

So I guess I would have to go to bwchiptune get my map reset back to stock then have this switchable map done and if it has to go back to bmw delete the codes myself and return map to std and get bwchiptune to delete the excess codes?

mr-modster · 12-04-2013, 04:08 AM

Can you not buy a computer thats cheaper? An do these things from home surely theres cheaper computers an software?

SO8 · 12-04-2013, 04:09 AM

Just to complicate things there are - I believe - others ways that BMW are finding out a car has been mapped ... though I am unsure what they are.

nicktyler · 12-04-2013, 09:38 AM

To turn the map abck to standard you need to take it to any indy with an autologic diagnostic computer. This will entirely rewrite it to the latest software leaving no trace of the previous map. Then you can have it mapped by a company like Evolve with a switch which leaves no noticable trace of the remap when you take it to the garage. I have done this with a 335i through the EvolveR cable and had no problem whatsoever and used the Bavarian Technic, official BMW software and it couldn't see any thing but the standard map.

I think you are being slightly paranoid about it. The garage are not going to go out of their way to dig deep through the files looking for any trace of a remap that you have told them is not there. If it is going to make you loose sleep then get it put back to stock and leave it.

Oh just to let you know. Not sure what part of Kent you are in but Prestige Vehicle Repairs http://www.prestigevehiclerepairs.com/ are a very good indy that have all the equipment to put your car back to standard quickly and good value too.

G82Dude · 12-04-2013, 10:36 AM

Map changes do indeed leave digital fingerprints. However, it is usually unlikely that a dealer would have the equipment or inclination to go out of their way too look. Unless they suspected foul play of course with a warranty claim, at which point they may involve BMW AG who most definitely can find out what has been done to the ECU(s).

Agreed. A friend of mine had a JB4 fitted and a BMW warranty. Warning light came on after a few thousand miles. Cleared all codes, took the JB4 off then waited for the light to come on again. It did, so he took it to BMW who diagnosed issues with the engine. They undertook all the warranty work with no problems. No mention of an aftermarket ECU was ever made...

mr-modster · 12-04-2013, 01:24 PM

Thanks soo much for the info guys im going to do what nicktyler has suggested get it put back to stock and have it remapped by evolve. Also will use that indy. Can someone point me in the direction to get an evolve remap cheers

I'd love a map or JB4 but for me it's just not worth it - as far as I know you can clear all error codes etc but adaptations will be there.

Warranty is for piece of mind if something big happens and you can bet your mortgage that if that happens, your engine goes bang and you're facing a £5k+ bill they will dig deep

gIzzE · 12-05-2013, 02:42 PM

BMW Germany logs the amount of times the ecu has been written by BMW, you can wipe all the codes but if Germany looks at the ecu counter and the car has more ecu writes than they have logged they will suspect.

If they ask I would just say you had some coding done and the latest software was written to the car.

It is hard for them to prove it, unless you admit it of course, difficult not to if you're honest though.
