    Hi all,  after months of waiting my vw Touran petrol auto is finally being built.

    It was ordered and test driven as a 1.4 petrol auto but this has been replaced with the new 1.5 petrol.

    Trouble is I am seeing some bad reports about this engine throughout the VW group.  Anyone have the 1.5 petrol or know anything about the problems?

    Apparently the engine is very jerky and kangaroos at low speed. Any help appreciated.

    Regards, Wonky

    I cancelled my 1.5 TSi DSG Touran because of the delays so never got to use the 1.5 TSi.

    That said there are some on this forum who have the 1.5 in the Golf and tell us it’s a brilliant engine, to date.

    Low speed jerking sounds like a DSG box thing and is common amongst DSG users though for me it was never a problem in my two Golf, one Seat Leon and now KIA DSG but I know folk complain about this.

    One thing to remember is on forums and in particular specialist forums you hear about the few problems but then because mass hysteria sets in much like drone’s at airports.

    I wouldn’t worry if I was you but I’m sure someone who uses this engine as I think forum user Mike has one in a Golf will be along soon.

    Apart from there are no VW Touran’s 1.5 engines that I’m aware of on the road yet in the UK.

    The 1.5 TSi engine has had this problem across the VAG company.  A software update is due by the beginning of March, according to a Skoda forum I use.

    Hope that helps

    With the amount of cars vag group makes it’s likely just software update, either gearbox or engine

    Ive never had any problems with dsg boxes being jerky.

    Hi Philjb,  thanks for comments.  I also drive a vw dsg box at present in an Alhambra and it is great.

    The reports I have read relate to the vw 1.5 tsi petrol engine, the fact I’ve ordered it with auto box might be a red herring.

    Did a little bit of reading up on the EVO problem and not a word found on my old MK7Golf forum but did find a couple of forums reporting problems with the 1.5 EVO in various VW models with manual gearboxes so you should be fine as everyone with DSG VW EVO seem to be happy with their cars.

    As noted by yourself, myself and Phil we’ve had no problems with the Kangaroo pull away that some DSG users seem to have or have reported in the past.

    Hi Mike11, that’s great to hear,  would you say you were getting 35 mpg around town?

    Hi Mike11,  thanks,  I’m looking at the 150 bhp petrol and live in town. At present my 2.0 ltr. Diesel Alhambra auto , only gives 33 ish around town, so anything better will be good.

    You should see a small improvement in mpg if you drive it sensibly, it’s just loaded up on a run you may find it struggles a bit up long hills.

    We had a 2.0 Mazda petrol if it was just one or two people and you feathered the throttle and pulled away slowly you could see about 42 ish mpg but it was so boring.

    But if you wanted to keep up with motorway traffic, loaded up it went down to about a real world 28mpg and was quite noisy. That you couldn’t speak to rear passengers without shouting.

    That was a 6 saloon.

    Since then I’ve gone back to tdi’s and mid 40 – 50 mpg and no worries loaded right up. It just goes.

    Hi Philjb,  interesting!  I hadn’t thought about what you mention. I am very used to my Alhambra diesel pulling away fully loaded with ease. The reason I’m

    going back to petrol is because I do a lot of around town and the diesel regeneration is suffering.  I can press the accelerator and get out of any trouble even fully loaded.

    Glad I didn’t get a diesel it’s 9p a litre more than petrol around here and the noise levels

    Even at 9p more per litre (even though it won’t stay like that for much longer) your diesel engine will still be more more efficient and deliver more miles offsetting the cost difference.

    Problem is, it’s eggs all over again.

    I have the Alhambra 2L 184 dsg and to get round the regeneration issue I just give it the beans in 2nd & 3rd on the dual carriageway (manual mode) once a week & that solves it totally, it’ll do 70 in 3rd easy, 50-60 seconds sat at high revs once a week cleans out the dpf & hardly makes a difference to overall economy.

    I have not once had a problem with diesel regeneration and my last car only did ~9,000 miles due to being a manual which I could no longer (medically) drive, so was only used primarily for short distances. I think, the few who do have issues shout loudest and people hear them and not the majority who have no issues.

    I do agree with you there.

    When it’s not going wrong peeps don’t create a fuss about not having problems!

    Car does the regen thing after turning off about once a week, spoke to VAG mechanic friend of mine & he says they all do it on a pre-programmed  cycle it’s just most people don’t notice it that’s all & I have to say that once I knew that I did keep an ear out for it & he’s correct (unusual for a VAG employee to not be telling porkies but there are some).

    +1 same here Ford Kuga diesel 11000 miles in 19 months all less than 30 miles local, not quite as bad as 9000 in 3 years.

    Unfortunately I do get confused and get things wrong, so I apologise in advance.

    I must admit I have never had a problem with the particulate filter regenerating either.

    However, when it does the regeneration, there is such a huge puff of white smoke out of the exhaust, that you would think a new Pope had been elected!

    Hi all,  I’m finding all the posts helpful.

    On the diesel regeneration point , my auto Alhambra tells me it’s not happy because it holds in 3rd gear and won’t change up when it normally would, around town.

    I then do what the Seat garage advised me, get on motorway for 10 miles @2000 rpm. I hold it in 4th gear to achieve this. The car is then ok for a couple of weeks around town.  Because I don’t normally do the motorway this time of year I find doing the regeneration a problem.

    This is main reason I am changing back to petrol. Although I am worried about the power and mpg in the proposed Touran, even though it’s lighter than the Alhambra. I am very suspicious of salesmen telling me the Touran 1.5 petrol will be fine. Nobody has driven one yet!

    As stated already the 150bhp diesel Alhambra pulls well, even fully loaded.

    Regards, wonky

    Only once did I need a friend to run regeneration software on our touran 184 dsg and that’s because no matter what I did the light wouldn’t go out.

    I must admit vw said nothing about this when we bought it.

    Then one mechanic admitted that if you drive it to break mpg records you’ll have loads of problems. You need to drive them like you stole them from time to time to regenerate the filter.

    It seems to be the higher output engines that are a problem?

    But I do regular long journeys to visit my kids. So it’s not been a problem for me.

    I don’t think I could go back to a big car with a small petrol engine.

    We did test drive a dsg sharan 1.4 and it was the most gutless car I’ve driven. That was forever kicking down to try and keep up with traffic.

    The Kodiaq was the same but smoother as long as you drove slowly. But the sales man said he’d been away to Cornwall for a week in this patrticuar car, loaded up and the average mpg was showing 25 mpg ?

    Hi Philjb,  that’s a good bit of info.  I was considering the 1.4 petrol Sharan dsg

    but cant find one to test. I am also concerned about the 1.5 petrol in the Touran when loaded.  I do like the size of the Alhambra/ Sharan, it’s just the regeneration problem.  Maybe I will pretend I’ve nicked mine as you suggest!

    Hi Wonky

    In the past 12 months, my wife got the Golf SV 1.5 (130bhp auto) on motability nad I got the Kodiaq 1.5 (150bhp auto) on private lease. Both great cars and engines, the 130bhp is smoother and 10mpg more economical.

    But I love the extra power on the 150bhp esp. when overtaking although it’s much thirstier.

     

    No problems at all, go for it! You won’t look back… Diesels are dead by the way, forget about them.

    I hope this helps!

    Totally agree Chris well said diesels are more economical on the motorway but not on a roads and in the town as for the price increase in diesel fuel how do you know Rapster it won’t increase more ? I’ve never read such rubbish 9000 miles in 3 years I’m amazed you didn’t have DPF problems and I’m sure the service manager at my VW dealer would be as well ! My nieces husband bought a year old Mercedes C Class diesel he had DPF problems from the start because he just travels to work 5 miles he had to swop for a petrol Mercedes !
