Just sold my Ford Focus last week.
The resale value is fuck.

Good bye Ford. 

My battery was changed during my second service.
Is that too soon?

If you didn't lock the car, some of the electronics may be using the battery power. When the engine is already switched off, the display still have the lights on. When the car is locked, the lights on the display are all off.

May I ask what prompted the clutch change?

An update on the new tyres that I have replaced last Sunday (Yokohama Bluearth AE50). Previously on stock Goodyear Assurance Fuelmax tyres. 205/60 R16 tyres.

Perhaps the Yokohama tyres are still new. Comfort and quietness of the AE50 felt better than the Goodyears. However, in terms of stability, the AE50s seem to be slightly inferior than the Goodyears, maybe due to the softer rubber of the Yokohamas. In the corners or bends(at higher speeds), the stability and control are slightly inferior than the Goodyears as it shows slightly more wobble. However, it is not exactly a criticism. Just an observation when in comparison to Goodyear tyres.

In normal to moderate driving, no issues in stability and performance. For those who are more into enthusiastic or spirited drives, it may be a better idea to avoid the Yokohamas. However, if you want comfort, quietness and good grip in the wet at a rather affordable price of below RM300 for each tyre (the tyres are tested to have superior braking on wet roads when compared to other competitors), you may consider the Yokohama Bluearth AE50s.

Pertaining to the purchase of car battery outside that will cause the warranty of the TCM to be void, I have made an inquiry to the Customer Service and they informed that it is indeed true that owners need to change the battery at the service centre to have the 10-year warranty on the TCM intact. However, I think it may be a grey area as a service adviser at the PJ service centre mentioned that the warranty will still be valid provided the battery spec is on par or better than the original Ford Focus battery (CCA). However, after I interrogated him further if what he said is really true, he changed his mind and said it is better that owners change the battery at the service centre to avoid any problems with the warranty claim on the TCM as there are cases whereby some owners have used a lower spec battery and got into problems with the warranty claim.

Now, the question is this. Have any owners who have changed to another battery outside of the service centre (non-original Ford battery) but with similar or higher spec experienced any issues with the electronics? The service adviser mentioned that the settings of the electronics will go haywire when the battery is replaced, and the electronics will need to be reset every time the car gets a new battery. Any owners here who have changed the battery outside of the service centre would care to comment?

The battery at the service centre was said to cost about RM890. Outside is about RM300 which is less than 3 times the price.
