118D or 120D, are the engines different?

Postby mef » Fri, 12 Feb 2010 07:20:43 UTC

Hi everyone, this is my first post on this forum!

I'm looking at buying a 1 series diesel and am currently considering a dec 2006 (56 plate) 118D or a Aug 2006 (06 plate) 120D. I have test driven both and I can certainly feel that the 120D is considerably faster, pulls better etc. but the 118 I looked at was a nice car, deove well, reasonably quick for a diesel, cheaper road tax and insurance, costs less and has done 10K less miles. Both the above cars have done around 100K miles but fully serviced ex company cars, well looked after examples with prices around £7k.

My questions are:

where does the extra 33Bhp come from in the 120, is the engine exactly the same?
Is the extra power purely down to the ecu mapping or are there other differences?
Can the 118 be re-mapped to bring it upt to the 120 power level or even more? ( I understand a 120 can be brought up to 200bhp)

Thanks in anticipation for your help,

Martin

The engine is same as in the block

The turbo's and injectors are different - which is where the power comes from.
There are other differences in drivetrain.

120d has bigger brakes Front and Rear

OK, thanks for the quick reply.

I'll have to have a think about it then, I liked the extra power and torque of the 120D I must admit! The 118D seemed quite powerful and flexible until I drove the 120D which was notably better, its just a case of wether I can justify paying £500 more for a car thats slightly older and has done more miles, dearer to insureand dearer for road tax!

Cheers,

Martin

So, maybe I'd be best off with the newer and lower running cost 118D and get it re-mapped to release a bit more power/torque and flexibility?

Well, for a change I was sensible and I went for the 118D in the end. I collected the car this morning and all seems well, it's great to drive and nice to be driving a well balanced RWD car again after so many years with FWD hatchbacks!

I'm still thinking about the possibility of getting the re-map work done by www.e-maps.co.uk I spoke to Simon last week and he quoted £300 for re-mapping the 118d to about 155bhp, that would make it similar to the 120D but at a lower cost than having bought a 120D and lower running costs.

I just wondered what people thought, has anyone any experience of such conversions, is it worth it and how does it effect the fuel consumption?

Thanks,

Martin

I'm in a similar boat mef - looking at either an A3 2.0 TDI (140bhp), 118d, or 120d. If I were to go for a 118d it'd be the earlier engine though and really think I'd struggle with only 122bhp...

Did you test an A3 at all and if so how did it compare?

we've had 2 A3's

last of old shape (03) and a 54 plate S Line DSG - they are very nice cars.

My old (8L) 2003 version was a lovely car - i do miss it
the DSG car was also nice and good spec but suspension was hard as nails and fuel economy rubbish

The 1er drives excellent and is very conifdent on the twisty roads.

Good to see you on here Martin. I have been reading of you're 118d remap too, glad it goes well. Just beware of the additional clutch wear and tear.

cheers

Hi Sean,

I drive the 118D fairly sensibly as it's mainly for knocking about, going to work and travelling around for work, ie a workhorse. I have some other nice cars for driving "briskly" ! the re-mapped 118d is brilliant, I'm glad I got it done, it's so much more flexible.

I'm in a similar position.

What spec was your 118d that you bought OP? How well had it handled the 100k miles?

I really fancy a 120d M-sport.

Cheers. :)

That's exactly what I ended up with! Couldn't be happier with it, and despite what I've read I actually find the drive quite smooth (even on RFL's), certainly smoother than my e46 Sport.

MUCH prefer this engine to the Audi 2.0TDI lump and it won me over. Ours has done 88k and runs like a charm, has clearly been looked after as well as bodywork is immaculate.

My 118D is the basic ES model, now done 104K and drives like its done 30K !! It's superb, I'm well pleased with it, having had it re-mapped its now very torquey and pulls really well, I'm getting about 42mpg on a tankful with mixed driving, economy is certainly no worse since the re-map but it's much better to drive.

the engine of the 120d is silky smooth and with a re-map a bit of an animal. Down the twisty back roads into my village the 1er is much fun.
Really don't know what i'd have next ....123d is the obvious upgrade

On a long run the 1er is very comfortable and very capable.

I've found a nice 56 plate 118d M-sport in blue for £11k with 58k miles. I'd like a 120d M-sport, but the only one I found for a similar price didn't have a full service history and had 74k miles

I am tempted to go for one with over 100k miles and save some money, but can these engines be trusted unlike the E46 engines?

mine had been serviced by an indy before i bought it with only 43k on it. Hence BMW had put it out to trade
or it would have been 2k more than what i paid.

78k on her now and still very pleased with it. I get it serviced at my local indy
and supply what parts i want fitting

Whats the BHP of a 118D. In the 'overview ' thread it says its 122bhp. And thats a figure ive found elsewhere. However im looking at the BMW Magazine Autumn/Winter 2009 and it gives the Bhp as 143. Why the discrepancy and who's right. (Im considering buying a 2006 118D).

Someones mentioned an average of 42mpg for a re-mapped 118d. Thats about exactly the same as my re-mapped 320D Tourer. Im surprised the 118d is not better than the 320d.

The facelift 118d from 2007 has 143bhp and the efficiency dynamics start stop thingy with lower o2 higher mpg etc. The 120d got a bhp upgrade too. I'd like one of these facelift 118ds but they are too expensive at the mo.
