    Question about wire gauge for line booster

    Hi all, The CLOC D I have says to use a 18Guage wire for the power feed, which I want to run from a fuse tap on the duse board. From what I can see online, 18AWG equates to a diameter of around 1mm. My maths tells me that a wire with diameter 1mm would have a cross section of around 0.8mm2...

    Questions about amps

    Looking for some help from you knowledgeable folk! I have a B7 rear amplified system. Now fed off an aftermarket HU but needed to use a HiLo from the HU direct speaker outs rather than the pre-amps HU outs. System is feeling low on base and a bit tinny. So, was thinking need a sub or...

    Sharing some VCDS/OBD2 data...

    Hi all, I'm very interested in the various VCDS/OBD2 data you can get, but sometimes its hard to know a reference point (and therefore diagnose things). For example, I noted that my long term fuel trim (on throttle/mult on block 32 or on an OBD II device) changes quite a lot with ambient temp...

    Help with wiring and Rear volume

    I've recently got a replacement (Android style) head unit which replaces my concert II. The car is an A4 avant style with rear amplified speakers (front driven directly from HU). Having connected it up and got it all working ok, my rear speaker volume is very low (but the sound is clear). I've...

    How to disable bluetooth phone

    I have OEM bluetooth phone in my car (with MFSW etc) - Seat Exeo ST 2010. I have just added an aftermarket HU, and the MFSW seem to be getting a bit confused as it operates both at the same time. I want to just disable the bluetooth phone to check that I am happy with the Android HU phone...

    DAB aerial options?

    Would like to get DAB in the car and understand that one of the key things is the aerial. I have a Exeo ST (or B7 A4 Avant) - what options do I have that give me decent signal? Are any of the internal mounted aerials any good? Can I use my existing internal aerials with some kind of...

    Looking for 2.0T VCDS Misfire logs...

    Whenever I do some logging I seem to get the occasional misfire, can be cylinders 1,3,4 (so blocks on 015/016). Depends on the driving, but 'normal driving' something like one of the cylinders might show a misfire every several minutes. I would like to compare this to others to see if this is...

    Can you test the N276

    Just wondering if there are tests to see if the N276 is ok? Either with VCDS or Multimeter? I note that block 103, 2 has something relating to fuel pressure regulator, but can anyone explain what this is and what this should be reading?

    Fuel pressure tester for 2.0T

    Was wondering about a manual gauge to read the fuel pressure, as interested to do some testing/learn a bit more about this. If I get a fuel pressure tester with a schrader valve attachment, does this attach onto the valve on the hpfp? By attaching to this point, does it only read the low...

    Anyone got some spare parts to borrow (MAF etc)?

    Just wondering if anyone here had a spare working MAF, possibly spare low pressure sensor too, that they would be able to and happy to lend (2.0T Petrol)? For all the VCDS logging I've done, I would quite like to swap out my part for a test part and double check a few things on them (rather...

    Replacing an 8 speaker system with a 10 speaker Bose...

    I'm wondering exactly how much of a pain this is to do in an Avant. I know many people say you could spend your money on better stuff, but if i could get hold of a Bose system for around a hundred quid I thought it still might be worth it to jeep the OEM styling?? As far as i can see getting...

    Throttle body question (2.0t) - should it close all the way?

    I have a question - which is probably a daft one, but should the throttle body (2.0t) close all the way when the car is off? On my previous car (1.8t) I know it did close completely when the car was off so the butterfly was at 90 degrees to the housing. I took off my throttle body to give it...

    N75 duty cycle query

    I'm in the process of doing a range of logging on my 2.0T (BWE 197bhp - stock/unmapped) and one thing (of several!) that has caught my eye as maybe being running out of spec (whether it is a result of other issues or the component itself I don't know) is the N75. In my logs a few months on a...

    Is the occasional misfire normal

    I'm guessing that you shouldn't really get any misfires, but I've done some logging recently and have found that I get the occasional misfire on cylinders 1-3, never when the car is under heavy load, but sometimes immediately after a WOT run, or when cruising to a stop, idling etc. When I say...

    Possible Fuel Pressure issue - help diagnose please!

    Had my 2.0T a year (4 year old 197bhp BWE engine, 50k miles) and it has generally been running ok but with niggles. I get the feeling its a car that wasn't properly looked after before - more a case of someone not checking under the hood often, checking oil etc rather than thrashed. So, the...

    Clamps (hose, oetiker etc)

    Hi all Just wondering if people generally use hose clamps, or use OE oetiker clamps? Are there advantages of one over the other (other than catching your hand more if you have hose clamps everywhere!), does one hold pressure better? For hose clamps, are there particular brands which people...

    BKR7E or BKR7EIX opinions?

    Anyone here tried the NGKs BKR7E (copper) and the BKR7EIX (iridium) on a stock 2.0T or a remapped 2.0T (ideally stage 1) and can say if they felt any performance difference. According to the NGK website, the IXs have better performance (3.5/5 vs 2.5/5) and fuel economy (2.5/5 vs 1.5/5), same...
