MARKY46 Posted March 3, 2011 Report Share Posted March 3, 2011 Hi there.So here is my problemMy current AHW engine in my Lupo 1.4s has expired and needs replaced.I managed to find a replacement AHW engine but found that the starter motor location was at the front of the engine and the starter position on my engine is at the back. I have since found out that although I have found an AHW engine, there is a difference with it in that there would appear to be two types of AHW engine. One that was fitted to the Lupo/Polo and has the starter at the back, and one that was fitted to the Golf and has the starter at the front!!! Both are known as AHW engines!!!Now here is the main question.I have read elsewhere on this forum that the best engine to replace the ageing AHW engine with is the BBY engine. What I would like to find out is if this engine is the same as the AHW in that there are two different types, one with starter at back like I need and one with starter at the front??And if this is the case, how are they distinguished from each other?? Surely there must be a difference to the codes or something so you know what each engine is designated for?? I'm not going to be able to see the engine before purchase so need to know if there is a way to tell which BBY is for the Lupo.All help in this matter would be greatly appreciated.Thanks in advance for all replies.....

Norpan Posted March 6, 2011 Report Share Posted March 6, 2011 The AHW cant be replaced by a BBY from a Polo 9N cause, as yo say the starter is located behindthe engine on yor AHW and Polo for ex. has it loctaded in front of the engine.Also, the bolt pattern for the gear box is different so your 085-gearbox wont fit on a BBY.The engine you can replace a AHW with is the AUA prom a Lupo or Polo 6n/6n2.It will fit perfect but there is one thing thats need modification. The EGR-valve is mounted atthe side of the head on AUA and on AHW it is on the exhaustmanifold.VW has thougt of it and there is a spare to buy from your orginalparts dealer, it´s a lid thatblocks the EGR hole in the head on AUA. Buy a new casket there as well. Quote Link to comment Share on other sites More sharing options...
MARKY46 Posted March 6, 2011 Author Report Share Posted March 6, 2011 Thanks for the reply NorpanThats very interesting what you have said as it would appear to be completely different to what I read on the below post.http://forums.clublupo.co.uk/index.php?showtopic=48066I'm getting now that I don't know what option is best!!!Is there anyone out there who has successfully managed to transplant either a AUA or a BBY engine into a Lupo that originally had a AHW engine??All replies greatly appreciated...

MARKY46 Posted March 7, 2011 Author Report Share Posted March 7, 2011 Has anyone got anymore thoughts, opinions on fitting an AUA engine as a replacement for an AHW engine?? Does anyone have any ideas what the name of the part that Norpan speaks about above that I would need to get from the dealer?? Quote Link to comment Share on other sites More sharing options...

MARKY46 Posted March 8, 2011 Author Report Share Posted March 8, 2011 (edited) Thats great info. ThanksI'm in the process just now of looking for an AUA engine but there are a few things I'd like to know??Are you 100% positive that the AUA engine with be a straight forward swap with no fitting/mounting problems except for the req'd blanking plate??Does the AUA engine need to come out of a Lupo or will any AUA engine be alright to fit?? Is there a particular year of engine that I would need to get??Does it matter about the gearbox whether its manual or automatic??Thanks once again in advance...

MARKY46 Posted March 21, 2011 Author Report Share Posted March 21, 2011 I'm not disputing that the BBY engine was never in the Lupo but from what I've seen you can't replace the AHW engine with one as there are differences. What I'm looking to find out is if the AUA can replace the AHW. I've been told above that it can but has anyone out there actually done it and if so, what do I need to know about where the AUA engine comes from as per the questions I was asking Norpan in the above reply?? Please help..... Quote Link to comment Share on other sites More sharing options...
