    Let’s talk about galvanic corrosion.

    I invite this conversation from a position of needing to know rather than knowing. Years ago I would have cited rust as my car DIY nemesis. However I got good at rust; faced with oxy it melts. Put aluminium next to steel and galvanic corrosion occurs. The resulting aluminium oxide has more...

    New Jack

    I occasionally have problems getting a jack and rubber pad under the A2 but that isn't the reason I bought a new jack. Little Dog is getting a new engine but I need my lockup clear and that has in it a broken sports car. I just can't get anything under it so can't fix it, so can' get it out...

    Metric thread coil kit

    I've lost lots of threads on my A2 to galvanic corrosion. The steel screw comes out and brings the aluminium female thread with it. Not had this yet but apparently the screws can shear off. Also lost threads due to age related use fatigue. The fix is to drill out and coil a new thread. I have...

    AMF clutch friction plate

    My clutch judders a little so I suspect a minor oil leak at the main crank seal. I will be needing a clutch. This one came attached to the AMF I'm preparing: It looks quite meaty to me, I have 8mm overall thinness and 2mm of friction material above the rivets. I've checked the manual and...

    Engine Stand

    Has anybody got one of these? An engine stand, I’m preparing a used AMF to go into my A2 next spring. I thought one of these may make the engine easier to work on and also to move around until the car is ready to take the engine. Concerns I have, perhaps it won't be easy to move but the...

    Oil contaminated glow plug

    Any thoughts as to what may be going on here. Glow plugs usually come out clean with a little carbon on them. The plug from no 3 cylinder is absolutely soaked with engine oil. Any thoughts on how it may have got there?

    How-to flare a brake pipe.

    Increasingly our A2s are failing MOT tests due to corroded brake pipes. Members are sourcing Audi pipes and having pipes made but sourcing pipes is becoming more difficult. Some members have advised that it is better to make your own pipes and I would agree. Facing this task for the first...

    Gear cables.

    I've just been browsing the market place and it struck me how popular two gear cables are. I can understand that because now they are NLA a breakage could finish off your A2. However looking at 7Zap both cables are the same part number so why would anybody need two spares? I've only ever read...

    20 years my daily

    It's 20 years to the day that I sat in the showroom at Leeds Audi and signed the order form for Little Dog. He was a replacement for a 12 month old A2 that had been lifted under the B post while in for warranty work and ruined. Needless to say I got this replacement at a very good price. 20...

    How does a tandem pump work?

    This is a genuine question, I don't know. What I do know is that there are two sides to the pump; hence tandem. One side supplies fuel to the injectors, the other side draws air and creates the vacuum for the brake servo and I guess also the vacuum operated valves around the engine? The side...

    Finding and preparing a new to me AMF

    I've put this in the technical section because once I find an AMF the thread will turn technical very quickly. Also the reasons for rejecting engines will be technical. Admin feel free to move the thread if I have missed the mark. My owned from new AMF has fallen victim to the glow plug data...

    Are all AMF engines the same?

    I ask because I’m going to need one and A2 AMFs are quite rare. My first question relates to the timing belt tensioner. I have already passed on a suitable engine because it has a hydraulic damper / tensioner. My engine has a friction damper and have already bought a timing belt kit. Are early...

    20Nm + 90 degrees, Renew = Torque to yield bolt?

    Not necessarily is the answer and, while best practice would be to follow the manual and renew, money can be saved by reusing screws that have not been stretched beyond their elastic limit. I noticed this some time ago when buying bolts for my A2 and Golf. Both the same part number, golf...

    AMF cam bearing and injector overhaul.

    I've run my A2 from new on completely the wrong oils. I have preferred a 5W-40 oil to the recommended 0W-30 oil. My logic was simple, the car has been used frequently for towing and otherwise spent the remainder of its life driven hard and fast on a motorway or fast A road. I've been told on...

    Front seat base swap.

    I'm planning the next job on Little Dog. At 170k miles the drivers seat base has become soggy and cover is beginning to wear on the outer edge. The passenger seat base though is firm and the cover in reasonable condition. I've checked 7Zap and it appears that the cover and foam both have one...

    TDi flexi exhaust pipe failure.

    Yes I know @froggy has a good thread on this subject but leaving my car three days in Lancs, assuming I can get home and get back for it is not pushing my buttons. After a 400 mile blast when Little Dog exceeded 60 mpg for the first time ever he blew his flexi. My question is, does anybody have...

    Little dog playing up again. This time it's rustling noises from just one speaker.

    A new development that completely has me beaten and I don't know where to start. When the engine is running there is a rustling noise from the N/S rear door speaker. It appears worse when the car is moving but that could be because it is distracting me from driving: It is just the one...

    Self locking hub nuts.

    I used the hub nuts and a 3/4 ratchet to maneuver the car into the garage recently to repair the engine. I've replaced them to ensure the hubs are torqued correctly. Do these nuts only self lock on one side? The one that hasn't locked was removed from the drivers (RH) side,

    How to recycle a 1J0973702 2 pin connector.

    These connectors have multiple applications around an A2 and they get damaged from time to time. Each new set of front brake pads comes with a 1J0973702 fitted with stiff solid copper wire. If you can replace this wire you can reuse the connector taken from an old pad.

    G 052112A3 hot bolt paste

    I'm in 7 Zap looking for part numbers for gaskets and seals for a repair that I have ongoing. I opened the wrong parts list and spotted item 12 hot bolt paste: I thought I'll have some of that; got exhaust related jobs on other cars to get done. Errr, no I won't: Does any body know what...
