Hi All,

I have recently bought a 2009 BMW 325i SE Coupe, E92 model, right hand drive (as I am in the UK).

I have generally found it a wonderful car to drive, except for one slight issue. If I am driving at speed (80+ MPH) then occasionally the car feels almost difficult to control. It feels like it is being buffeted by high winds and sometime difficult to keep within its lane on the motorway. If I am driving around 60 or 70 MPH there are no problems.

Now, I fully appreciate I should not be driving at 80+ on the UK motorway, but having just got the car I've been hoping try it out at speed.

My last few cars were Audis and I've made the leap back to BMW after almost 20 years and this is the only negative point of the whole renewed experience with BMW.

Any guidance would be most appreciated.

Thanks,

MP

Definitely uncharacteristic. The most likely causes are tramlining (which is fixed by changing to better tires) or the need for a four-wheel suspension alignment. I would start with the latter.

Don't overlook simple things like tire pressures. One tire that's low could contribute to this.

I'm suspecting worn suspension parts. This is NOT the way a BMW is supposed to handle. As mentioned in here, your recommended tire PSI (kPa?) should be 'spot on' to your door placard recommendation although I'm doubting this is the root cause (unless you've really abused your pressure maintenance!).

Are your replacement tires according to BMW's recommendation? Isn't that mandatory in the U.K.?

When was the last time you had an alignment and had the suspension parts checked for integrity...any worn parts, bushings?

PS: Do you in (Britain?) also have difficulty with certain Welsh automotive terminology? :angel:

Hi All,

I wanted to give you an update on what was the cause of this problem I mentioned yesterday, which was that the car drove fine on test drives, which did not exceed 70 MPH, it was only after I bought the car and opened it up on the motorway that I notices the problem.

So, this morning, after reading all your great advice, I booked a session into a local tyre / alloy dealership specialising in performance cars. It took them 5 minutes to figure out that the problem was with the cheap tyres so I had 4 new Goodyears fitted. It emerged that the previous owner had put some very cheap run flat types on the rear of the car, presumably just to get it sold. OK, it cost me a few more £££ than I had expected but the difference when I got the car out on the motorway was incredible! I now have the car I wanted...

Many thanks for your advice and help in getting this matter dealt with - and thanks for your patience with what was clearly a beginner's error.

Cheers!
