    Bora TDi 115 Mass Air Flow?

    I've been reading around the forum hear and it's starting to look like my Bora TDi 115 is suffering with the mass air flow problem. I get real flat spots in power from about 2500rpm upwards in 3rd or above. 1st and 2nd seems to be prety much fine.

    Where's the best place to get a mass air flow meter from for a TDi 115? Also, I've seen mention of getting the codes cleared - what's meant by this and how/where would I get that done?

    Cheers folks

    Exchange it at your local stealers, should be around 80.

    for about 60 you can get a new MAF probe from gsfparts. (http://www.gsfcarparts.com/)

    So that sounds like the sensible thing to try. Cool.

    I've had a look on gsfcarparts but can't find anything on there for a bora [img]/ubbthreads/images/graemlins/frown.gif[/img]

    Give gsf (German Swedish & French) car parts a call, they'll quote you around 60 exchange. They can quote you if you give them the engine code, or alternatively the part number from te MAF unit itself. Its usually the Bosch MAF units that fail-Pieburg are pretty bomb proof. It's a simple procedure to remove and install the new one yourself. You'll only need a screwdriver and a decent pair of slip ring pliers/ groove joint pliers to undo the large spring clip. The MAF is a common fault, but don't assume it's that. Try to borrow a MAF unit from another car (with the same part number) or find a friendly parts supplier who'll let you try a MAF and return it if it proves not to be that causing the fault. I hope it is your MAF- it's the simplest snd least costly repair. They tend to get tired around 70/80K miles (generally) I've recently come across A3's Bora's Passat's which have problems with loss of power through the car going into limp mode and limiting the turbo's performance. This feels like you're towing a caravan, and you notice a loss of power (particularly going up hill) around 3000 rpm upwards. Switching off the ignition and restarting tends to cure the fault temporarily. If you have the fault codes read or "scanned" they usually plug either a VAGCOM or Sun/Snap-On or similar hand held machine into a port under the dash or below the ashtray or under the handbrake stowage bin (fitted in different positions depending on which car it is) This identifies the fault, gives the operator a text readout on a LCD screen along with a fault code which can be confirmed in a manual (or on the internet) If any codes are read, they can erase them from the memory and reset them, so that if the fault (or another) reccurs they can try to use the information to identify the fault. i.e. as a diagnosis. Many cars are now reporting " Inlet manifold pressure exceeded " and are proving impossible to cure. Anyone with any information to the contrary-i'd be very interested to hear from you. Good luck. Regards. Paul.

    Yes, all you need is the sensor probe not the whole unit. I got one for 40 + VAT and put into my A4 TDI, a 5 min job, the only tool you need is a anti-tamper torx screw driver or get a set of anti-tamper torx screw bits for your drill from Maplin.

    Re: Bora TDi 115 Mass Air Flow?

    Finally got round to ordering at the weekend and it arrived today. Fitted it in 10mins and have been for a little test drive. OMG what a transformation!!! No flat spot from 2500rpm so decent smooth acceleration all the way through the rev range which will making over taking a pleasure. And I was suprised to find that low end grunt has improved loads too making pulling away from standing more fun ;-)

    Bloody good 40 in my reckoning. Got the part from Euro Car Parts as it was 25 quid cheaper than GSF

    Re: Bora TDi 115 Mass Air Flow?

    Got another thing to update on this. Since fitting the replacement everything seemed to be sorted but not quite.

    I don't have the major loss of power from 2500rpm upwards but instead I now get a temporary blip in the power abywhere between 2500 and 4000rpm in 3rd or above.

    Is this new one dodgy, maybe not screwed in tight enough, or something else?
