Shock MOT Fail! - Tyres, drop-links and handbrake.

This is my third MOT since buying the car and the first time it has even come up with an advisory item, let alone a fail, but I guess it had to happen eventually. I took it back to Walsh Autos in Birkenhead who know me and are usually very fair, but I think the problem was the 5-series hadn't been washed in about 12 months and was absolutely caked with bird muck and grime. It looked like it had been standing under a tree for that time and the fresh tax-disc didn't help, so I guess the tester thought I was dragging her out to sell and was a bit harsh on the checks. The moral of the story here would be to always give the car a wash prior to an MOT so the car appears cherished.

The fail items were:

Both N/S Tyres tread too low - I went for top-of-the-range Nexen nBlue through work with our trade discount, which worked out at £50 each for 225/55/16. This was still slightly cheaper than the low-range Pirelli and Continental and had a much better spec - extra-load, higher-speed, quieter and with an eco-rating, so I let my usual tyre-snobbey slip and plumped for good budget ones. If cash had been tighter though, lower-range Nexen and the worringly named Achilles budgets could be had for as little as £32. Still, £100 for 2 tyres is still good, considering the price for one entry-level Pirelli at Kwik Fit is £124.50!

O/S Anti-Roll Bar Drop-Link rubber boot perished - It was the original and had begun to let dirt in, so I figured the N/S one wouldn't be far behind and replaced both. The N/S one appeared to have been replace a few years ago and was in good nick, but when it's a matched pair of something - shocks or top-mounts - it's best to renew both at the same time. This is a problem that would have been avoided had the previous owner replaced both, but I guess this is easy to say when doing the work myself and not leaving it at BMW after the MOT. The drop-links were £9 each, again through work, but can be bought for a similar price on eBay.

I won't be needing to put a guide up on how to do the front drop-links, as our mate Clint @ E21Build.com has already done one for his daily-driver E39 540i - http://www.e21build.com/2013/06/diy-changing-e39-front-swaybar-end-links.html. Also check out his awesome E21 3-series engine-swap and drift-car build and, of course, my E21 stance-car build - http://e21dub.blogspot.com.

O/S Parking-Brake efficiency little or no effort - I tightened up the handbrake last year, but it soon started to loosen off again. It's a heavy car, so the cables or inner brake-shoes will likely need replacing at some point. To get it through the test, I cranked the cables up a bit and adjusted the shoes as far as they would go, using the method in this older post - . That was a week ago,

O/S No. Plate Light not working - Turned out to be a 5W festoon type bulb, which I had a few of lying around, so didn't cost anything. Be careful when popping the lens out, it does not press in from the side with the recess, as that would be too obvious - it presses in from the opposite side!


The overall cost for the MOT repairs was £120, so not bad at all really. It was the tyres that cost the lion's share and without them this would have been very cheap indeed, but they had to come round eventually. Even so, the money I saved by doing the work at home speaks for itself - throwing the car into a dealership I estimate to have come to £400+
