About 18 months ago I ditched my Mk4 GTi in favour of a lovely spec 2013 e92 320d. Now for various reasons, mainly the shifting of financial priorities towards things like houses and weddings (but also because I have gotten pretty bored driving a big heavy diesel) I am considering selling the e92 and going back to my Golf as my daily drive.
I just have a few questions about the Mk4 as I am now a bit out of touch with the VAG scene, and I would be very grateful for any guidance:
1. Remapping - although the 320d didn't feel particularly fast, it is a quicker car than the Golf (the 150bhp engine in my case) so I am considering a remap to keep things interesting. Am I correct in saying that the 180bhp engine is effectively the same engine as the 150bhp but with a more aggressive ECU map, meaning that I should be able to achieve close to 180bhp with a conservative remap with relative ease?
2. Related to the above, is there any kind of OEM remap or performance upgrade available for this car (like the performance pack option they have for the Mk7 for example)? I know OEM remaps tend to be more conservative than aftermarket but in my experience they are also more palatable to insurers, which is why I would be leaning towards one if possible.
3. Exhaust - similar to the above, are there any OEM exhaust options for this car, like the performance exhausts that BMW make as retrofit options for certain of their models? If not, can anyone recommend a good aftermarket exhaust?
4. Can anyone recommend a good place (online) to buy (i) OEM parts (for the various boring bits I need to replace like the glove compartment cover and brake lights, etc.); and (ii) aftermarket parts (if I get tempted to add something a little different to the car)?
5. Performance generally - I'm struggling to find a consistent answer to this, but does anyone have any reasonably accurate 0-60 times for this car, in both the 150bhp and 180bhp variants? According to Wikipedia the 180bhp engine does 0-60 in 6.4 seconds, but that sounds a little ambitious to me...
Any help appreciated!
Thank you!
