Did you buy genuine Speed Sensors? I bought one from a well-known spares retailer, and it gave me exactly what you described: fine for a while and then lots of warnings. In the end, I went and got one from VW, (second mortgage), since then no issues

A few weeks ago, I returned to my car to find an error message stating that the ACC was inoperative. On checking, I found that somebody had attempted to steal it. I guess they might have been disturbed as they had managed to remove it from its bracket, but did not get away with it. However, it still cost me nearly £400 to get it repaired and recalibrated. I looked at ways to prevent it in the future, or at least to make it more difficult. My son, who is into 3D printing, made up a cover that fits over the sensor and is fixed to the grill, currently with cable ties, but he wants to develop a more secure way of fixing it. It has quite an OEM look and only time will tell if it is effective.

Just had a quick check on Euro Car Parts, the two sensors are around £300 for the pair, and judging by my local dealer, they probably are charging an hour's labour for the £450

Yes I had to, driver's door, roughly £160 by the VW dealer

Years ago, the thinking was that spacers put extra strain on wheel bearings as they moved the axis of suspension away from what was designed, nobody seems to be worried about this any more, so I wonder if it is a problem

Not sure on the legality of replacing HIDs with LEDs, it is illegal to put LEDs in place of Halogen bulbs, in short that is because the bulbs need to be 'E marked' and the legislation that covers that is written for filament bulbs. Is it legal to replace halogen with LED bulbs? - Ask the Car Expert

I fitted Osram Xenarc Nightbreaker Laser D3S to mine, a great improvement but still could do with a bit more light at times. The D3 bulbs are not the best, I remember a company that does a conversion using higher power bulbs, but can't find them.

Would have liked to come, but away that weekend

The only LED replacements I have seen, replaced the Mk7 Standard halogen headlamps.

I have formatted my card in the past, the files that are unique to the Sat Nav are hidden, so should still be there, Did you use FAT32 or NTFS as the format protocol?. NTFS allows for a slightly larger file, which I used as FAT only gave me a 13GB card and the file was 14/15 GB, although now VW have reduced the Europe file to allow the 13GB card to be used. Suggest you try a reload of the map, if that doesn't work reformat and use the DiscoverCare software, it is slower, but I have found it more robust.

There is no separate bulb for Main Beam, there is a shutter that comes down to create the Dipped Beam pattern, if there is no change, then the shutter is at fault.

Poor earth connections often give warnings, if I understand correctly both Indicator and Fuel Cap are in the same area.

A lot of time where there are intermittent flickering of lights, it is down to corrosion on terminals or on older cars a poor earth

The Golf has an intelligent charging system, so you need to connect one lead to the battery post and the other to the metal tag on the other end near the bulkhead, so that the system knows the state of charge of the battery. I don't lock the car in the garage, but simply put the bonnet down loosely.
