Growing up in the later years of the twentieth century and being a bit of a car nerd, I can fondly remember the glossy adverts for the latest models. Each brand seemed to have their own identity.
Everyone knows Audi was vorsprung durch technik even though we had no idea what it meant, progress trough technology apparently. My Grandfather made a fleeting appearance in an ad for the Audi 80, as the hapless ships captain dropping the car from a millionaires yacht into the Mediterranean. Audi's boast of the car being made from galvanised steel meant it wouldn't rust, was offset by my Grandfather reporting the car was ruined by the time they'd fished it out, off camera of course.
Ford had a catchy jingle to go with Everything we do is driven by you. Volkswagen had the famous Changes advert. A recent divorcee played by model Paula Hamilton, throwing away her possessions until finding her car key. She smiles and drives off in her Golf to the caption: If only everything in life was a reliable as a Volkswagen.
Land Rover has been The best 4x4 by far for as long as I can remember and Fiat's Hand built by robots slogan was cheekily rewritten by the comedy show Not the Nine O'clock News to: Designed by lasers, built by robots, driven by Italians accompanied by a picture of a motorway pile up.
BMW, with their rear wheel drive saloons have always marketed itself as The Ultimate Driving Machine. Adverts would be testosterone filled speed fests, with chiselled males and beautiful girls in exclusive parts of the world. These adverts appealed to a certain type of person which according to YouGov is:
"Male, aged 40-59, lives in East Anglia. They’re likely to hold right wing political views and work in the business, finance or consulting sectors. Your typical BMW driver is interested in motorsports and motoring, and enjoys dining out."
I think we might all add that BMW drivers tend to view indicators as an unusable optional extra but I digress.
So with this owner profile you may be surprised to learn that when we had to replace my wife's rusty Honda HRV, given that it had gained the structural integrity of a lace doily, we went for a BMW X3. The reasons were eminently sensible. It's a 4x4 SUV, it's a comfortable drive, it's an automatic, and most importantly it was cheap.
BMW X3 |
So from an ownership point of view I was expecting a relatively easy time, and yet the Ultimate Driving Machine is at times a royal pain in the behind.
With my mechanical skills best described as enthusiastic amateur, I have tackled the following jobs:
- Full Service and Oil Change. Relatively simple and the car ran much better afterwards.
- Replacement of faulty Air Bag Sensor. A real pain having to disassemble the passenger B-Pillar trim. The part is discontinued and took a while to source.
- Repair Vacuum Leak 1. The rubber intake boot split allowing unmetered air into the engine. This caused the car to run rich with poor fuel consumption. I ordered a new part from the BMW dealer and dismantled the engine ready to replace it. I then discovered my own car had an oil leak and I couldn't drive to pick the part up. I got the train which took three hours, I had to change at Carnforth and then had a three mile walk from the station in the rain to collect the part. I got very wet, but the car got repaired.
- Repair Vacuum Leak 2. A rubber pipe at the bottom of the engine perished causing high fuel consumption again. This time I ordered a part to be delivered from a specialist. Trouble was it never came. I managed to find one from a motor factor 50 miles away in Leeds and had to drive there to collect it.
- Replace front brake pads. A simple job, that caused no drama.
Let me explain.
The car has a screen wash reservoir in the front under the bonnet. It has two pumps, one for the windscreen and one for the rear, so far so standard. The rear washer jet is supplied by a 6mm pipe that runs from the reservoir to the rear through the car under the carpet. Again nothing too unusual in that except, BMW in their infinite wisdom decided to make the pipe in two sections. The joint is on the drivers side of the transmission tunnel and is a push fit.
So what? I hear you ask, well the problem is this.
When there is cold weather, the rear jet freezes. When the rear screen wash is activated the pressure forces the joint apart. As the now broken pipe is lower than the reservoir the entire watery contents leak into the rear footwell, where it soaks into the foam sound deadening material and rots the carpet.
Moreover, this pipe cannot easily be reached, that would be too sensible. No, no, instead you must remove the rear seat, the drivers seat (remembering to disconnect the battery so the airbag system doesn't fault), and all of the surrounding plastic trim. You then peel back to sodden carpet to reveal a small lake and the gushing joint.
The Offending Joint |
Repair is the next problem.
The first time, I spent hours drying the carpet with a halogen heater and the hairdryer. I simply pushed the joint back together. It clicked and I thought no more of it.
Two weeks later it broke again. This time I glued the joint. That repair lasted a month.
This time I meant business. I taped with PTFE tape, glued and for extra piece of mind clamped another larger hose over the top.
Summer came, the car dried out and I felt I had cured the problem, until this week when the weather went cold and the screen wash disappeared. Yet again we have a leaking joint.
So what is the solution? Ultimately a new piece of pipe from pump to jet without a joint. That would involve removing the interior of the car completely and in the current freezing temperatures is not appealing. I could send it to BMW who charge £500 to effect a repair without a guarantee it won't do the same again once the weather goes cold. Instead I'm going to use a coupling that is used by water dispensing fridges. They use 6mm pipe and it is possible to get a fitting to join two pieces of pipe together. You have to order online as no one appears to stock them, believe me I trawled the local plumbers merchants and DIY stores. I event went to a shop that sells fridges.
